   sometimes it makes me wonder how gentoo manages their ebuilds.
   portage and maven both supports transitive dependencies, but somehow
   the portage ebuilds which can be compared to the maven pom is more
   stable and reliable. currently the number of portage ebuilds is
around 24,000+,
   a large amount of ebuilds to maintain.

   i'm guessing the community plays a crucial part in the health of the
   the gentoo community has a lot of passionate people taking care of
the ebuilds.
