Sorry, maybe the docs are a bit scattered, but since we are used to it,
we end up not noticing some omissions or bad organization (we actually
know the organization is bad, but fixing it, you know...).

Here's a quick summary:

* The CHICKEN core (compiler, interpreter, runtime system, profiler,
  eggs manager) code is maintained in a git repository (see for info about how to get it).

* Eggs can be hosted by the subversion repository at or,
  more recently, on remote VCSs (see  When eggs are not hosted
  by the svn repository at, you probably can find the egg
  repository location in the egg documentation
  (<the-egg>).  If the egg author has not
  provided that information in the egg documentation (he/she should),
  you can find it out by looking at the egg-locations file
  -- empty password)

* You can also get eggs source code with chicken-install:

      $ chicken-install -r the-egg

  If you want some specific version:

      $ chicken-install -r the-egg:the-version

  If you want to get the tests too:

      $ chicken-install -r -test the-egg

tl;dr: provides guidelines about how to obtain
code hosted on  For eggs hosted remotely, check the egg
documentation or the egg-locations file.  You can quickly and
VCS-agnostically get eggs source code with chicken-install.

Nice.  Thanks for your interest in contributing.

Best wishes.
