tazpkg view modules/tazpkg-find-depends @ rev 811
Update documentation (attempt to describe all the commands both with all options). Strongly need to review and update translations and docs! Add TazPkg help system for commandline (based on the HTML docs). Attempt to drop all package lists but "packages.info". Small improvements and code prettify.
