+xbps - xtraeme's binary package ystem.
 
-It is a simple build package system that installs packages inside of
-a chroot in a destination directory. Once the package has been installed
-into this directory, you can make it appear/unappear at the master directory
-at any time. It's in spirit the same than GNU stow, but the files are just
-copied (there are no soft/hard links).
+xbps is a new binary package system, taken ideas from other free available
+implementations, such as dpkg/apt, RPM, pacman and others. Metadata handling
+as package databases are handled by proplib. Multiple compression formats
+are supported in binary packages thanks to libarchive.
 
 xbps has been designed for Linux, and for the moment I'm not interested to
-make it work on any other random OS. I've been a NetBSD developer for some
-years and I do not want to come back... also the experience has helped to
-me to start xbps and not to use pkgsrc, which is very portable but also
-not so fast.
+make it work on any other random OS. xbps is the base to create a basic
