NAME
     gzexe -- create auto-decompressing executables

SYNOPSIS
     gzexe [-d] file ...

DESCRIPTION
     The  gzexe utility uses gzip(1) to compress executables, producing executa-
     bles that decompress on-the-fly when executed.  This saves disk  space,  at
     the  cost of slower execution times.  The original executables are saved by
     copying each of them to a file with the same name with  a	`~'  suffix  ap-
     pended.   After verifying that the compressed executables work as expected,
     the backup files can be removed.

     The options are as follows:

     -d      Decompress executables previously compressed by gzexe.

     The gzexe program refuses to compress non-regular or non-executable  files,
     files  with  a  setuid or setgid bit set, files that are already compressed
     using gzexe or programs  it  needs  to  perform  on-the-fly  decompression:
     sh(1), mktemp(1), rm(1), echo(1), tail(1), gzip(1), and chmod(1).

SEE ALSO
     gzip(1)

CAVEATS
     The  gzexe  utility  replaces  files by overwriting them with the generated
     compressed executable.  To be able to do this,  it  is  required  that  the
     original files are writable.
