combined into a single archive file.

It can be used, though, for any similar purpose.
.sp
key___ is one character from the set drtux_____,
optionally concatenated with v_.

The names_____ are constituent files in the archive file.
The meanings of the key___ characters are:
.sp
d_ means delete the named files from the archive file.
.sp
r_ means replace the named files in the archive file.
If the archive file does not exist, r_ will create it.
If the named files are not in the archive file, they are appended.
.sp
t_ prints a table of contents of the archive file.
If no names are given, all files in the archive are tabled.
If names are given, only those files are tabled.
.sp
u_ is similar to r_ except that only those
files that have been modified are replaced.
If no names are given, all files in the archive that
have been modified will be replaced by the modified version.
.sp
x_ will extract the named files.
If no names are given, all files in the archive are
extracted.
In neither case does x_ alter the archive file.
.sp

BUGS		Option
vt__ should be implemented as a table with more information.

directory to a random number.
