+# Tazpkg - Tiny autonomus zone packages manager.
+#
+# This is a lightwight packages manager for *.tazpkg files, all written in
+# SHell script. It works well with Busybox ash shell and bash. Tazpkg let you
+# list, install, remove, download or get information about a package, you can
+# use 'tazpkg usage' to get a list of commands with a short description. Tazpkg
+# also relolv dependencies and can upgrade packages from a mirror.
