One final note. Currently there is no GUI for this package, so any usage will have to be done from the command line only. It is discouraged to use the default tce-* scripts and this package manager interchangeably as certain cache files will not get placed when using the tce-* scripts. This can be resolved by calling 'pax -z' beforehand, but it is an extra step that most will forget. If you want to make pax your default manager, run 'pax --install' and it will walk you through the process.
I'm working on the man page for this project now and will include it in the next release. Running 'pax --help' should provide you enough information to successfully use the software though. DM me with any questions you may have.
