gzexe - compress executable files in place

The _g_z_e_x_e utility allows you to compress executables in
place and have them automatically uncompress and execute
when you run them (at a penalty in performance). For
example if you execute ``gzexe /bin/cat'' it will create the
following two files:
-r-xr-xr-x 1 root bin 9644 Feb 11 11:16 /bin/cat
-r-xr-xr-x 1 bin bin 24576 Nov 23 13:21 /bin/cat~
/bin/cat~ is the original file and /bin/cat is the self-
uncompressing executable file. You can remove /bin/cat~
once you are sure that /bin/cat works properly.
This utility is most useful on systems with very small
disks.

----dddd Decompress the given executables instead of compressing
them.

The compressed executable is a shell script. This may create
some security holes. In particular, the compressed
executable relies on the PATH environment variable to find
_g_z_i_p and some other utilities (_t_a_i_l, _c_h_m_o_d, _l_n, _s_l_e_e_p).
BBBBUUUUGGGGSSSS
_g_z_e_x_e attempts to retain the original file attributes on the
compressed executable, but you may have to fix them manually
in some cases, using _c_h_m_o_d or _c_h_o_w_n.
