9e is a program to explore Plan9 archives. You can do whatever you
like with the source so long as you clearly indicate all modifications
and the author responsible for each.

Usage Summary:

$9e [options] ...

Options:

-h: dump headers only
-v: dump file names and sizes while extracting
-r: specify alternate root directory
-?: help

If no file is named on the command line, standard input is assumed.
Note that the input file must be a decompressed archive (decompress
with gzip).
