-# On macOS the sha1 tool is named 'shasum' while on all other unix systems it is called 'sha1sum'.
-# In order to make all unix provioning scripts run on macOS without special case handling
-# a symbolic link is created.
-# The shasum tool is a perl script which does some globbing to determine the perl version. The
-# symbolic link has to point directly to the binary including the perl version.
-# Additionally the CI seems to have multiple parallel perl versions installed which causes
-# multiple shasum tools to be present (shasum5.16, shasum5.18).
-#
-# Currently this is
-#     /usr/local/bin/sha1sum -> /usr/bin/shasum5.18
