+                    GNU GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
+
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
+
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
+
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Use with the GNU Affero General Public License.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If the program does terminal interaction, make it output a short
+notice like this when it starts in an interactive mode:
+
+    <program>  Copyright (C) <year>  <name of author>
+    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, your program's commands
+might be different; for a GUI interface, you would use an "about box".
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU GPL, see
+<https://www.gnu.org/licenses/>.
+
+  The GNU General Public License does not permit incorporating your program
+into proprietary programs.  If your program is a subroutine library, you
+may consider it more useful to permit linking proprietary applications with
+the library.  If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.  But first, please read
+<https://www.gnu.org/licenses/why-not-lgpl.html>.

+
+# 注意！我发现电脑开机后第一次测速延迟会明显偏高（手动 TCPing 也一样），后续测速都正常
+# 因此建议大家开机后第一次正式测速前，先随便测几个 IP（无需等待延迟测速完成，只要进度条动了就可以直接关了）
+
+# 软件在 默认参数 下的整个流程大概步骤：
+# 1. 延迟测速（默认 TCPing 模式，HTTPing 模式需要手动加上参数）
+# 2. 延迟排序（延迟 从低到高 排序并按条件过滤，不同丢包率会分开排序，因此可能会有一些延迟低但丢包的 IP 排到后面）
+# 3. 下载测速（从延迟最低的 IP 开始依次下载测速，默认测够 10 个就会停止）
+# 4. 速度排序（速度从高到低排序）
+# 5. 输出结果（通过参数控制是否输出到命令行(-p 0)或输出到文件(-o "")）
+
+# 注意：输出的结果文件 result.csv 通过微软 Excel 表格打开会中文乱码，这是正常的，其他表格软件/记事本都显示正常

+## \# 进阶使用
+
+直接运行使用的是默认参数，如果想要测速结果更全面、更符合自己的要求，可以自定义参数。
+
+```Dart
+C:\>cfst.exe -h
+
+CloudflareSpeedTest vX.X.X
+测试各个 CDN 或网站所有 IP 的延迟和速度，获取最快 IP (IPv4+IPv6)！
+https://github.com/XIU2/CloudflareSpeedTest
+
+参数：
+    -n 200
+        延迟测速线程；越多延迟测速越快，性能弱的设备 (如路由器) 请勿太高；(默认 200 最多 1000)
+    -t 4
+        延迟测速次数；单个 IP 延迟测速的次数；(默认 4 次)
+    -dn 10
+        下载测速数量；延迟测速并排序后，从最低延迟起下载测速的数量；(默认 10 个)
+    -dt 10
+        下载测速时间；单个 IP 下载测速最长时间，不能太短；(默认 10 秒)
+    -tp 443
+        指定测速端口；延迟测速/下载测速时使用的端口；(默认 443 端口)
+    -url https://cf.xiu2.xyz/url
+        指定测速地址；延迟测速(HTTPing)/下载测速时使用的地址，默认地址不保证可用性，建议自建；
+        当下载测速时，软件会从 HTTP 响应头中获取该 IP 当前地区码（支持 Cloudflare、AWS CloudFront、Fastly、Gcore、CDN77、Bunny 等 CDN）并显示出来。
+
+    -httping
+        切换测速模式；延迟测速模式改为 HTTP 协议，所用测试地址为 [-url] 参数；(默认 TCPing)
+        当使用 HTTP 测速模式时，软件会从 HTTP 响应头中获取该 IP 当前地区码（支持 Cloudflare、AWS CloudFront、Fastly、Gcore、CDN77、Bunny 等 CDN）并显示出来。
+        注意：HTTPing 本质上也算一种 网络扫描 行为，因此如果你在服务器上面运行，需要降低并发(-n)，否则可能会被一些严格的商家暂停服务。
+        如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而 触发临时限制机制，因此才会过一会儿就恢复了，建议降低并发(-n)减少这种情况的发生。
+    -httping-code 200
+        有效状态代码；HTTPing 延迟测速时网页返回的有效 HTTP 状态码，仅限一个；(默认 200 301 302)
+    -cfcolo HKG,KHH,NRT,LAX,SEA,SJC,FRA,MAD
+        匹配指定地区；IATA 机场地区码或国家/城市码，英文逗号分隔，大小写均可，仅 HTTPing 模式可用；(默认 所有地区)
+        支持 Cloudflare、AWS CloudFront、Fastly、Gcore、CDN77、Bunny 等 CDN
+        其中 Cloudflare、AWS CloudFront、Fastly 使用的是 IATA 三字机场地区码，如：HKG,LAX
+        其中 CDN77、Bunny 使用的是 二字国家/区域码，如：US,CN
+        其中 Gcore 使用的是 二字城市码，如：FR,AM
+        因此大家使用 -cfcolo 指定地区码时要根据不同的 CDN 来指定不同类型的地区码。

+
+> 刚接触 CFST 的人，可能会迷惑**明明延迟测速可用 IP 有 30 个，怎么最后只剩下 3 个了呢？**  
+> 下载测速里的队列又是什么意思？难道我下载测速还要排队？
+
+CFST 会先延迟测速，在这过程中进度条右侧会实时显示可用 IP 数量（`可用: 30`），但注意该可用数量指的是**测试通过没有超时的 IP 数量**，和延迟上下限、丢包条件无关。当延迟测速完成后，因为还指定了**延迟上下限、丢包**的条件，所以按照条件过滤后只剩下 `10` 个了（也就是等待下载测速的 `队列：10`）。
+
+即以上示例中，`321` 个 IP 延迟测速完成后，只有 `30` 个 IP 测试通过没有超时，然后根据延迟上下限范围：`40 ~ 150 ms` 及丢包上限条件过滤后，只剩下 `10` 个满足要求的 IP 了。如果你 `-dd` 禁用了下载测速，那么就会直接输出这 `10` 个 IP 了。当然该示例并未禁用，因此接下来软件会继续对这 `10` 个 IP 进行下载测速（`队列：10`）。
+
+> 因为下载测速是单线程一个个 IP 挨着排队测速的，因此等待下载测速的 IP 数量才会叫做 `队列`。
+
+****
+
+> 你可能注意到了，**明明指定了要找到 5 个满足下载速度条件的 IP，怎么才 3 个就 “中断” 了呢？**
+
+下载测速进度条中的 `3 / 5`，前者指的是找到了 `3` 个满足下载速度下限条件的 IP（即下载速度高于 `1 MB/s` ），后者 `5` 指的是你要求找到 `5` 个满足下载速度下限条件的 IP（`-dn 5`）。
+
+> 另外，提醒一下，如果你指定的 `-dn` 大于下载测速队列，比如你延迟测速后只剩下 `4` 个 IP 了，那么下载测速进度条中后面的数字就会和下载测速队列一样都是 `4` 个，而非你 `-dn` 指定的 `5` 个了。
+
+软件在测速完这 `10` 个 IP 后，只找到了 `3` 个下载速度高于 `1 MB/s` 的 IP，剩下的 `7` 个 IP 都是 “不及格” 的。
+
+因此，这不是 `“每次测速都不到 5 就中断了”`，而是所有 IP 都下载测速完了，但却只找到了 `3` 个满足条件的。
+
+****
+
+还有一种情况，那就是当可用 IP 很多时（几百几千），你还设置了下载速度条件，那么可能就会遇到：**怎么下载测速进度条老是卡在 `X / 5` 了呢？**
+
+这其实并不是卡住了，而是只有当找到一个满足条件的 IP 时，进度条才会 +1，因此如果一直找不到，那么 CFST 就会一直下载测速下去，因此在表现为进度条卡住不动，但这也是在提醒你：你设置的下载速度条件对你来说已经高于实际了，你需要适当调低预期。
+
+****
+
+如果不想遇到这种全部测速一遍都没几个满足条件的情况，那么就要**调低下载速度上限参数 `-sl`**，或者移除。
+
+因为只要指定了 `-sl` 参数，那么只要没有凑够 `-dn` 的数量（默认 10 个），就会一直测速下去，直到凑够或全部测速完。移除 `-sl` 并添加 `-dn 20` 参数，这样就是只测速延迟最低的前 20 个 IP，测速完就停止，节省时间。
+
+****
+
+另外，如果全部队列 IP 都测速完了，但一个满足下载速度条件的 IP 都没有，你可能需要调低预期的下载测速下限条件，但你需要知道当前的大概测速速度都在什么范围，那么你就可以加上 `-debug` 参数开启调试模式，这样再遇到这种情况时，就会**忽略条件返回所有测速结果**，你就能看到这些 IP 的下载速度都有多少，心里也就有数了，然后**适当调低 `-sl` 再试试**。
+
+> 注意，如果你**没有指定**下载测速下限 `-sl` 条件，那么无论什么情况下 CFST 都会**输出所有测速结果**。
+
+同样，延迟测速方面，`可用: 30`、`队列：10` 这两个数值也可以让你清楚，你设置的延迟条件对你来说是否过于苛刻。如果可用 IP 一大堆，但条件过滤后只剩下 2、3 个，那不用说就知道需要**调低预期的延迟/丢包条件**了。
+
+这两个机制，一个是告诉你**延迟丢包条件**是否合适的，一个是告诉你**下载速度条件**是否合适的。

+
+Windows 要指定参数需要在 CMD 中运行，或者把参数添加到快捷方式目标中。
+
+> [!TIP]
+> - 各参数均有**默认值**，当使用默认值时参数可以省略（**按需选择**），参数**不分前后顺序**。  
+> - Windows **PowerShell** 只需把下面命令中的 `cfst.exe` 改为 `.\cfst.exe` 即可。

+#### \# CMD 带参数运行
+
+对命令行程序不熟悉的人，可能不知道该如何带参数运行，我就简单说一下。
+
+<details>
+<summary><code><strong>「 点击展开 查看内容 」</strong></code></summary>
+
+****
+
+很多人打开 CMD 直接就以**绝对路径**运行 CFST 会报错，这是因为默认的 `-f ip.txt` 参数是相对路径，需要指定绝对路径的 ip.txt 才行，但这样毕竟太麻烦了，因此还是建议进入 CFST 程序目录下，以**相对路径**方式运行：
+
+**方式 一**：
+1. 打开 CFST 程序所在目录  
+2. 空白处按下 <kbd>Shift + 鼠标右键</kbd> 显示右键菜单  
+3. 选择 **\[在此处打开命令窗口\]** 来打开 CMD 窗口，此时默认就位于当前目录下  
+4. 输入带参数的命令，如：`cfst.exe -tl 200 -dn 20` 即可运行
+
+**方式 二**：
+1. 打开 CFST 程序所在目录  
+2. 直接在文件夹地址栏中全选(或清空)并输入 `cmd` 回车就能打开 CMD 窗口，此时默认就位于当前目录下  
+4. 输入带参数的命令，如：`cfst.exe -tl 200 -dn 20` 即可运行
+
+> 当然你也可以随便打开一个 CMD 窗口，然后输入如 `cd /d "D:\Program Files\cfst"` 来进入程序目录
+
+> **提示**：如果用的是 **PowerShell** 只需把命令中的 `cfst.exe` 改为 `.\cfst.exe` 即可。  
+> **注意**：在 **PowerShell** 下使用 `-o ""` 会被忽略掉空参数导致报错，可加个空格 `-o " "` 解决
+

+
+#### \# Windows 快捷方式带参数运行
+
+如果不经常修改运行参数（比如平时都是直接双击运行）的人，建议使用快捷方式，更方便点。

+
+右键 `cfst.exe` 文件 - **\[创建快捷方式\]**，然后右键该快捷方式 - **\[属性\]**，修改其**目标**：
+
+``` bash
+# 如果要不输出结果文件，那么请加上 -o " "，引号里的是空格（不加空格会导致该空参数被忽略从而报错）。
+D:\ABC\cfst\cfst.exe -tl 200 -dn 20 -o " "
+
+# 如果文件路径包含引号，则需要把启动参数放在引号外面，记得引号和 - 之间有空格。
+"D:\Program Files\cfst\cfst.exe" -tl 200 -dn 20 -o " "
+
+# 注意！快捷方式 - 起始位置 不能是空的，否则就会因为绝对路径而找不到 ip.txt 文件

+# 指定自带的 IPv6 数据文件可测速这些 IPv6 地址
+# 另外，v2.1.0 版本后支持 IPv4+IPv6 混合测速并移除了 -ipv6 参数，因此一个文件内可以同时包含 IPv4+IPv6 地址
+cfst.exe -f ipv6.txt
+
+# 也可以直接通过参数指定要测速的 IP
+cfst.exe -ip 1.1.1.1,2606:4700::/32

+
+#### \# HTTPing
+
+<details>
+<summary><code><strong>「 点击展开 查看内容 」</strong></code></summary>
+
+****
+
+目前有两种延迟测速模式，分别为 **TCP 协议、HTTP 协议**。  
+TCP 协议耗时更短、消耗资源更少，超时时间为 1 秒，该协议为默认模式。  
+HTTP 协议适用于快速测试某域名指向某 IP 时是否可以访问，超时时间为 2 秒。  
+同一个 IP，各协议去 Ping 得到的延迟一般为：**ICMP < TCP < HTTP**，越靠右对丢包等网络波动越敏感。
+
+> 注意：HTTPing 本质上也算一种**网络扫描**行为，因此如果你在服务器上面运行，需要**降低并发**(`-n`)，否则可能会被一些严格的商家暂停服务。如果你遇到 HTTPing 首次测速可用 IP 数量正常，后续测速越来越少甚至直接为 0，但停一段时间后又恢复了的情况，那么也可能是被 运营商、Cloudflare CDN 认为你在网络扫描而**触发临时限制机制**，因此才会过一会儿就恢复了，建议**降低并发**(`-n`)减少这种情况的发生。
+
+> 另外，本软件 HTTPing 仅获取**响应头(response headers)**，并不获取正文内容（即 URL 文件大小不影响 HTTPing 测试，但如果你还要下载测速的话，那么还是需要一个大文件的），类似于 curl -i 功能。
+
+> 另外，HTTPing 过程中，软件会从 HTTP 响应头中获取该 IP 当前地区码（支持 Cloudflare、AWS CloudFront、Fastly、Gcore、CDN77、Bunny 等 CDN）并显示出来，而 TCPing 过程中无法这样做（但 下载测速 时也会这样做来获取地区码，毕竟下载测速也是个 HTTP 链接）
+
+``` bash
+# 只需加上 -httping 参数即可切换到 HTTP 协议延迟测速模式
+cfst.exe -httping
+
+# 软件会根据访问时网页返回的有效 HTTP 状态码来判断可用性（当然超时也算），默认对返回 200 301 302 这三个 HTTP 状态码的视为有效，可以手动指定认为有效的 HTTP 状态码，但只能指定一个（你需要提前确定测试地址正常情况下会返回哪个状态码）
+cfst.exe -httping -httping-code 200
+
+# 通过 -url 参数来指定 HTTPing 测试地址（可以是任意网页 URL，不局限于具体文件地址）
+cfst.exe -httping -url https://cf.xiu2.xyz/url
+# 如果你要 HTTPing 测试其他网站/CDN，那么指定一个该网站/使用该 CDN 的地址（因为软件默认地址是 Cloudflare 的，只能用于测试 Cloudflare 的 IP）
+
+# 注意：如果测速地址为 HTTP 协议，记得加上 -tp 80（这个参数会影响 延迟测速/下载测速 时使用的端口）
+# 同理，如果要测速 80 端口，那么也需要加上 -url 参数来指定一个 http:// 协议的地址才行（且该地址不会强制重定向至 HTTPS），如果是非 80 443 端口，那么需要确定该下载测速地址是否支持通过该端口访问。

+#### \# 匹配指定地区
+
+<details>
+<summary><code><strong>「 点击展开 查看内容 」</strong></code></summary>
+
+****
+
+Cloudflare CDN 的节点 IP 是 Anycast IP，即每个 IP 对应的服务器节点及地区不是固定的，而是动态变化的，**不同地区、不同运营商、不同时间段**访问**同一个 IP** 分配到的服务器节点地区和路线也都是不一样的（比如同一个 IP，美国人访问就是分配到就近的美国节点服务器，日本人访问则就又变成了就近的日本节点服务器了，国内内地就比较特殊了，只能给你分配到其他国家，当然不同的 IP 段路由变化/分配逻辑也是不同的，有的 IP 段会较为固定）。
+
+> **注意**！虽然 Cloudflare CDN 有很多亚洲节点，但**不代表你就能用上**，新加坡人测速可能随便一抓一大把的新加坡节点，但你全部扫一遍可能都遇不到一个，因为这是由 CDN 控制的。Anycast IP 的路由是经常变的，同一个 IP 今天可能是美国，明天你再访问可能就又分配到欧洲节点了（当然这只是个例子，一般没有那么频繁，这也和很多因素有关，比如线路拥塞程度，成本变动等），因此**不要对该功能有过高期待**~
+
+或者你随便找个 Cloudflare CDN 的 IP（比如官网域名的解析 IP `104.16.123.96`），然后去那些有全球节点的[在线 Ping 测试](https://ping.sx/ping?t=104.16.123.96)网站，你就会发现这个 IP 在全球大部分地区的延迟都是个位数（而且很多都是 0.X ms），就算一些地方延迟高一些但也基本都控制在 几十ms，只有在国内才会发现突然变成了 上百ms 了。
+
+这就是 Anycast 技术，也就只有国内大陆这种特殊的网络情况，才需要对 Anycast 的 CDN IP 进行优选。
+
+因此，对于这种 Anycast IP 的实际服务器位置，就不能靠那些在线 IP 地址位置查询网站来判断了。
+
+除了通过 **HTTP 响应头**获取地区码外（该功能的实现方式），还可以手动访问 `http://CloudflareIP/cdn-cgi/trace` 来获知 CDN 分配给你的实际节点地区码。
+
+> 该功能支持 **Cloudflare、AWS CloudFront、Fastly、Gcore、CDN77、Bunny** 等 CDN。  
+> 但注意，不是所有 CDN 都支持 Anycast 技术的，很多 CDN 会限制一个网站能使用的 IP 范围。
+
+> 其中 **Cloudflare、AWS CloudFront、Fastly** 都使用的是 **`IATA 三字机场地区码`**，如：HKG,LAX  
+> 而 **CDN77、Bunny** 使用的是 **`二字国家/区域码`**，如：US,CN  
+> **Gcore** 则使用的是 **`二字城市码`**，如：FR,AM  
+> 因此大家使用 `-cfcolo` 指定地区码时要根据不同的 CDN 来指定不同类型的地区码。
+
+> **注意**：如果你要用于筛选 AWS CloudFront CDN 地区，那么要通过 `-url` 参数指定一个使用 AWS CloudFront CDN 的下载测速地址（因为软件默认下载测速地址是 Cloudflare CDN 的），另外有时候 HTTPing 模式测速一些 AWS CloudFront 地址会返回 403 错误，这种情况下需要加上 `-httping-code 403` 才能正确获取地区码。
+
+``` bash
+# 指定地区名后，延迟测速后得到的结果就都是指定地区的 IP 了（如果没有指定 -dd 的话则会继续进行下载测速）
+# 如果延迟测速后结果为 0，则说明没有找到任何一个（未超时可用的）指定地区的 IP。
+# 节点地区名为当地 IATA 机场地区码或国家/城市码，指定多个时用英文逗号分隔，v2.2.3 版本后支持小写
+
+cfst.exe -httping -cfcolo HKG,KHH,NRT,LAX,SEA,SJC,FRA,MAD
+
+# 注意，该参数只有在 HTTPing 延迟测速模式下才可用（因为软件是通过 HTTP 链接中的响应头来获得该 IP 的实际地区码）
+
+# 另外，HTTPing 过程中，软件会从 HTTP 响应头中获取该 IP 当前地区码（支持 Cloudflare、AWS CloudFront、Fastly、Gcore、CDN77、Bunny 等 CDN）并显示出来，而 TCPing 过程中无法这样做（但 下载测速 时也会这样做来获取地区码，毕竟下载测速也是个 HTTP 链接）

+- 如果没找到任何满足条件的 IP，则会输出 **空**（如没有禁用下载测速，也会因为数量为 0 而跳过下载测速）
+
+****
+
+**指定了任何 下载速度条件 (`-sl`)：**
+
+且当 **关闭 调试模式** 时（即没加上 `-debug` 参数，这种情况下和延迟测速的逻辑完全一致）：
+
+- 如果找到最少 1 个满足条件的 IP，则只输出 **这几个满足条件的 IP**  
+- 如果没找到任何满足条件的 IP，则输出 **空**
+
+且当 **开启 调试模式** 时（即加上了 `-debug` 参数，延迟测速并没有加上下面第二条里的逻辑，所以依然输出 空）：

+#### \# 单独对一个或多个 IP 测速
+
+<details>
+<summary><code><strong>「 点击展开 查看内容 」</strong></code></summary>
+
+****
+
+**方式 一**：
+直接通过参数指定要测速的 IP 段数据。
+``` bash
+# 先进入 CFST 所在目录，然后运行：
+# Windows 系统（在 CMD 中运行）
+cfst.exe -ip 1.1.1.1,2.2.2.2/24,2606:4700::/32
+
+# Linux 系统
+./cfst -ip 1.1.1.1,2.2.2.2/24,2606:4700::/32
+```
+
+****
+
+**方式 二**：
+或者把这些 IP 按如下格式写入到任意文本文件中，例如：`1.txt`
+
+```
+1.1.1.1
+1.1.1.200
+1.0.0.1/24
+2606:4700::/32
+```
+
+> 单个 IP 的话可以省略 `/32` 子网掩码了（即 `1.1.1.1`等同于 `1.1.1.1/32`）。  
+> 子网掩码 `/24` 指的是这个 IP 最后一段，即 `1.0.0.1~1.0.0.255`。
+
+
+然后运行 CFST 时加上启动参数 `-f 1.txt` 来指定 IP 段数据文件。
+
+``` bash
+# 先进入 CFST 所在目录，然后运行：
+# Windows 系统（在 CMD 中运行）
+cfst.exe -f 1.txt
+
+# Linux 系统
+./cfst -f 1.txt
+
+# 对于 1.0.0.1/24 这样的 IP 段只会随机最后一段（1.0.0.1~255），如果要测速该 IP 段中的所有 IP，请加上 -allip 参数。
+```
+
+</details>
+
+****
+
+#### \# 下载测速都是 0.00 ？
+
+<details>
+<summary><code><strong>「 点击展开 查看内容 」</strong></code></summary>
+
+****
+**\#\# 原理简单解释：**
+
+首先要明白，CFST 下载测速过程，本质上和你将 `IP 下载测速地址域名` 写入 hosts 文件，然后浏览器去访问下载测速地址是一样的，只不过软件将其自动化了（类似于 `curl -I --resolve 下载测速地址域名:443:IP https://下载测速地址`）。
+
+因此如果下载测速结果全都是 0.00 MB/s，那么代表**下载测速过程中出问题报错**，导致直接终止测速了（并最终显示为 0.00），就只有这几种可能性：
+
+1. **下载测速地址有问题**
+2. **测速的 IP 地址有问题**
+3. **你的网络有问题**
+
+****
+
+**\#\# 调试模式排查：**
+
+接下来**请务必**先在你原先使用的 CFST 运行命令后**追加一个 `-debug` 参数来开启调试模式**，重新跑一遍测速，这样下载测速过程中出现任何报错都会显示具体原因方便你排查。
+
+常见的下载测速失败报错原因有（因为是 Go 语言的原生报错信息，因此基本都是英文）：
+
+1. `... read: connection reset by peer ...  `  
+**链接被重置**，可能是下载测速地址被阻断了 或测速 IP 被针对性 HTTPS 阻断了，可能是蔷干的，也可能是运营商干的（比如移动或部分地区的白名单），当然也可能是测速 IP 服务器单纯的重置了你这个不合法的链接请求
+2. `... HTTP 状态码: 403 ...`  
+像这种直接提示 **HTTP 状态码**的，比较好判断，如 403 就是下载测速地址禁止你访问，404 就是下载测速地址路径对应的文件找不到（具体其他的可以搜索 HTTP 状态码含义）
+3. `... context deadline exceeded (Client.Timeout exceeded while awaiting headers) ...`  
+这种一般是**请求超时**引起的，可能是 IP 或网络问题，也可能是 `-dt` 下载测速时间设置的太短了（当然默认的 10 秒肯定算不上短）
+4. `... tls: handshake failure ...` 或 `... tls: failed to verify certificate ...`  
+这种 **TLS 握手失败/SSL 证书错误** 代表下载测速地址和测速 IP 服务器不匹配，也就是下载测速地址与测速 IP 其中一方有误（例如下载测速地址是托管在 Fastly CDN 的，但测速 IP 是 Cloudflare CDN 的，或者反过来，总之就是你访问下载测速地址时该测速的 IP 服务器告诉你这个网站域名它不认识并把你拒之门外）
+5. `... tls: failed to verify certificate: x509: certificate is valid for XXX.XX, not YYY.YY ...`  
+这种是 **SSL 证书里没有包含你下载测速地址的域名**，要么是下载测速地址证书配置有问题，要么就是该测速服务器 IP 上并没有该下载测速地址域名对应的 SSL 证书，也就意味着这个服务器 IP 是不能用于该下载测速地址域名的（比如你用谷歌的服务器 IP 去下载测速百度的域名就会这样，或像上面 4 的原因一样）
+6. `... tls: failed to verify certificate: x509: certificate has expired or is not yet valid: current time ...`  
+这种是 **SSL 证书过期了或者尚未到有效时间**，除了这个原因外，也可能是和上面 4、5 的原因一样（这 4、5、6 三种报错可能会同时出现在同一个服务器 IP 上）
+7. `... tls: failed to verify certificate: x509: certificate signed by unknown authority.`  
+这种代表**系统证书配置有问题**，导致 TLS 握手时无法验证证书，目前只在 Termux 内遇到过（解决方法见：https://github.com/XIU2/CloudflareSpeedTest/discussions/61 帖子末尾）
+
+> 如果你遇到了其他报错原因，且翻译后还是不懂，可以发 Issues 或 Discussions 询问，我也会更新到这里。  
+> 但注意，发 Issues 或 Discussions 询问时，请记得带上**调试模式下 CFST 输出的完整内容（或者完整截图）**。
+
+根据上面的报错原因排查一遍后，如果还是无法解决，那么可以尝试下面这些进一步排查：
+
+****
+
+**一、下载测速地址有问题**：
+
+先去 [#490](https://github.com/XIU2/CloudflareSpeedTest/discussions/490) 找几个其他的下载测速地址都试试。
+
+如果其中有能下载测速出结果的，则就代表你之前使用的下载测速地址有问题（注意，目前默认下载测速地址仅为一个带负载均衡轮询的重定向链接，会自动重定向到上面帖子里大家分享的公益下载测速地址，而这些地址在**不同地区的可用性可能有差异**，因此可能出现之前不行现在又正常的情况，如果**想要稳定，建议自建**，上面帖子写了几种自建方法）。
+
+如果找了很多，都是一样 0.00，那么就要考虑其他可能性了。
+
+****
+
+**二、测速的 IP 地址有问题**：
+
+你用来测速的 IP 地址，可能一些 TCP 测试是通的，但实际上因为各种原因导致不能建立 HTTP 链接（比如是回源 IP，比如是企业用户专用 IP 等等），因此你可以多尝试一些其他的 IP 看是否可行。
+
+****
+
+**三、你的网络有问题**：
+
+这个就比较麻烦了，如果你现在是用电脑+宽带来使用 CFST 测速的，那么可以尝试关闭手机 WIFI 并打开流量，然后数据线连接电脑，设置好 USB 网络共享（不同手机系统不太一样，具体自行搜索哈），并拔掉电脑的网线，这样你的电脑现在就是走的手机流量数据网络了（如果手机流量数据和宽带不是一个运营商会更好排查），然后再次运行 CFST 测速看看结果是否改变（也可以同时尝试上面的排查方法来交叉验证）。
+
+如果测速结果正常了，那么显然就是宽带网络的问题，如果还是一样的 0.00，那么就麻烦了。。。

+## 手动编译
+
+<details>
+<summary><code><strong>「 点击展开 查看内容 」</strong></code></summary>
+
+****
+
+为了方便，我是在编译的时候将版本号写入代码中的 version 变量，因此你手动编译时，需要像下面这样在 `go build` 命令后面加上 `-ldflags` 参数来指定版本号：
+
+```bash
+go build -ldflags "-s -w -X main.version=v1.0.0"
+# 在 CloudflareSpeedTest 目录中通过命令行（例如 CMD、Bat 脚本）运行该命令，即可编译一个可在和当前设备同样系统、位数、架构的环境下运行的二进制程序（Go 会自动检测你的系统位数、架构）且版本号为 v1.0.0
+```
+
+如果想要在 Windows 64位系统下编译**其他系统、架构、位数**，那么需要指定 **GOOS** 和 **GOARCH** 变量。
+
+例如在 Windows 系统下编译一个适用于 **Linux 系统 amd 架构 64 位**的二进制程序：
+
+```bat
+SET GOOS=linux
+SET GOARCH=amd64
+go build -ldflags "-s -w -X main.version=v1.0.0"
+```
+
+例如在 Linux 系统下编译一个适用于 **Windows 系统 amd 架构 32 位**的二进制程序：
+
+```bash
+GOOS=windows
+GOARCH=386
+go build -ldflags "-s -w -X main.version=v1.0.0"
+```
+
+> 可以运行 `go tool dist list` 来查看当前 Go 版本支持编译哪些组合。
+
+****
+
+当然，为了方便批量编译，我会专门指定一个变量为版本号，后续编译直接调用该版本号变量即可。  
+同时，批量编译的话，还需要分开放到不同文件夹才行（或者文件名不同），需要加上 `-o` 参数指定。
+
+```bat
+:: Windows 系统下是这样：
+SET version=v1.0.0
+SET GOOS=linux
+SET GOARCH=amd64
+go build -o Releases\cfst_linux_amd64\cfst -ldflags "-s -w -X main.version=%version%"
+```
+
+```bash
+# Linux 系统下是这样：
+version=v1.0.0
+GOOS=windows
+GOARCH=386
+go build -o Releases/cfst_windows_386/cfst.exe -ldflags "-s -w -X main.version=${version}"
+```

+# XIU2/CloudflareSpeedTest - Script(脚本)
+
+这里都是一些通过调用 **CFST** 并**扩展实现更多个性化功能**的脚本。  
+
+****
+> [!TIP]
+> 我之所以将 CFST 制作为一个**命令行程序**，就是考虑到**通用性**，因为毕竟不可能把所有需求都塞到软件内（特别是一些**个性化、小众**的需求），这样增加维护难度和精力不说，还会导致软件异常臃肿（`“变成我讨厌的样子”`），而命令行程序的优势之一就在于**可以很方便的和其他软件、脚本搭配使用**。
+
+比如像下面这些我写的几个脚本，就是把一些需求以外置脚本方式实现。  
+
+> 即脚本调用 CFST 测速并获取结果，然后***按照自己的需求自由决定***如何处理得到的测速结果（比如修改 Hosts 等）。  
+
+总的来说，我写的这几个脚本都比较简单，功能也很单一，除了满足部分用户的需求外，***更像是一个 CFST 与脚本搭配使用的示例参考***，对于一些会写脚本、软件的用户来说，完全可以**自给自足**来实现一些个性化需求。
+
+当然，如果你有一些自用好用的脚本也可以通过 [**Issues**](https://github.com/XIU2/CloudflareSpeedTest/issues)、[**Discussions**](https://github.com/XIU2/CloudflareSpeedTest/discussions) 或 **Pull requests** 发给我添加到这里让更多人用到！
