  * slots allow several versions (branches) of one package to be installed simultaneously
  * masking - built in support for specification of supported build environments
  * USE flags
  * built-in distcc/ccache support
  * build packages without installing them
  * one of valid licenses in the ebuild
  * ebuilds are shell scripts that set variables, call and define functions
  * lots of helper functions, like enewuser and edos2unix
  * some support for FHS
  * eclasses - collections of macros
  * great documentation
  * can run on many Linux/BSD/Solaris systems
