2 # Tazwok - SliTaz source compiler and binary packages generator/cooker.

4 # Tazwok can compile source package and creat binary packages suitable for
5 # Tazpkg (Tiny Autonomus zone package manager). You can build individuals
6 # package or a list a packages with one command, rebuild the full distro,
7 # generate a packages repository and also list and get info about packages.
