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] <file> ...

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 Plan9 archive.
