# This is a prologue that allows to run a perl script as an executable

# On such systems, the usual invocation of an executable through execlp()
# or execvp() fails with ENOEXEC if it is a script that does not start
# with a #! line. The script interpreter mentioned in the #! line has
# to be /bin/sh, because on GuixSD systems that is the only program that
# has a fixed file name. The second line is essential for perl and is
# also useful for editing this file in Emacs. The next two lines below
# are valid code in both sh and perl. When executed by sh, they re-execute
# the script through the perl program found in $PATH. The '-x' option
# is essential as well; without it, perl would re-execute the script
# through /bin/sh. When executed by perl, the next two lines are a no-op.
