Listed are some of the projects I have been involved in.
SimpleArchiver is a tar-alternative written in C.
The latest version can store regular files, symlinks, and empty directories while keeping track of permissions and UID/GID.
(Note that UID/GID is only preserved if extracted as root.)
It can optionally compress files via flags to specify compressor and decompressor,
making this software compatible with any de/compressor that accepts data in standard-input and outputs data to standard-output.
This software is licensed with the ISC license.
