This is the user manual for urpkg, a software to install programs in a safe and easily undoable way. Urpkg is public-domain software, written in C.
I first begun working on urpkg after reading the More Control and Package Management using Package Users LFS hint so a lot of ideas implemented in urpkg come from the hint's author Matthias S. Benkmann which I would like to credit here.
Even though this document should be complete enough, I strongly recommend you to read the hint first, as to better understand the ideas behind urpkg.
