It is the hash containing the configuration.  Gitolite's configuration
file is just a piece of perl source code, in the form of:

--8<---------------cut here---------------start------------->8---
%RC = (

    # ------------------------------------------------------------------

    # default umask gives you perms of '0700'; see the rc file docs for
    # how/why you might change this
    UMASK                           =>  0077,

    # look for "git-config" in the documentation
    GIT_CONFIG_KEYS                 =>  '',

    [...]
);

# ------------------------------------------------------------------------------
# per perl rules, this should be the last line in such a file:
1;
--8<---------------cut here---------------end--------------->8---

So this field is verbatim added at the end of the hash, serving as an
escape hatch to configure properties not yet supported by the
gitolite-rc-file.

I realize the description of the field requires some knowledge of how
gitolite is configured, and I am open to suggestions on how to improve
it, if you have any. :)
