Changelog:
2015-04-26  v3.6.3  allow limited use of 'git config' using the new 'config'
                    command

                    accept openssh 6.8's new fingerprint output format

                    (finally!) allow limited symlinks within ~/repositories;
                    see commit 8e36230 for details

                    perms command now lists available roles

                    minor backward compat breakage: 'perms -l repo' no longer
                    works; see 'perms -h' for new usage

                    allow gitolite-shell to be used as $SHELL (experts only;
                    no support, no docs; see commit 9cd1e37 for details)

                    help with 'git push --signed' using a post-receive hook to
                    adopt push certs into 'refs/push-certs'; for details see
                    contrib/hooks/repo-specific/save-push-signatures

                    new 'transparent proxy' feature for git repos; see
                    src/lib/Gitolite/Triggers/TProxy.pm for details
