Ahh , very well
I see there's /main/gbc/gbc_archive.c but it looks internal/private is
there too much to do to update Uncompress to support listing and extracting
items or can gbc_archive be modified to extract items and work publicly?

I assume gambas itself (gbc) can unarchive because a gambas exe is an
archive (or am i wrong about that and it works differently?)

Note: not interested in adding/making archives just extracting.

Reason: I'm adding an update class to my progs that uses gitlab,
It checks version in .project file and downloads the archive if newer, then
extracts contents to update/compile source.
