Are you looking for files that have been compress(1)-ed, freeze(1)-d,
zip(1)-ed, gzip(1)-ed, bzip2(1)-ed, etc.?  The algorithms used differ.

I assume you *really* mean a "package" and not some other solution
to your problem (i.e. unpacking them outside *your* application).
If you want to be able to *write* to the packed files, then you obviously
either want them to be unpacked before you access them or "wrap" the
open/close with unpack/pack...  ?

Or, was the reference to "write" an overzealous typo?  :>

The sources to all of the compressors/decompressors in popular use
are readily available (though almost always written in C)
