'>   I am trying to track down some code that would allow a
'>   program of mine to archive a few files, much like PKZIP
'>   does and of course unarchive the files.  Does anyone know
'>   of or have any such code they would be willing to part with?
'>....
'   Here are some simple routines to bundle files in a single
'archival file. The interface is a bit unfriendly, but the thing
'works like a charm. You can add whatever interface suits you
'and fits the program you are writing. Have a look at it.
