  45 # or execvp() fails with ENOEXEC if it is a script that does not start
  46 # with a #! line.  The script interpreter mentioned in the #! line has
  47 # to be /bin/sh, because on GuixSD systems that is the only program that
  48 # has a fixed file name.  The second line is essential for perl and is
  49 # also useful for editing this file in Emacs.  The next two lines below

  51 # the script through the perl program found in $PATH.  The '-x' option

  53 # through /bin/sh.  When executed by perl, the next two lines are a no-op.
