-#!/bin/sh
-# gzexe: compressor for Unix executables.
-# Use this only for binaries that you do not use frequently.
-#
-# The compressed version is a shell script which decompresses itself after
-# skipping $skip lines of shell commands. We try invoking the compressed
-# executable with the original name (for programs looking at their name).
-# We also try to retain the original file permissions on the compressed file.
-# For safety reasons, gzexe will not create setuid or setgid shell scripts.
-
-# WARNING: the first line of this file must be either : or #!/bin/sh
-# The : is required for some old versions of csh.
-# On Ultrix, /bin/sh is too buggy, change the first line to: #!/bin/sh5
