    # Redirects mapping gitweb -> cgit
    # Inspired from: http://www.clearchain.com/blog/posts/cgit-upgrade-gitweb-retired
    #
    # Gitweb uses get targets seperated by ;
    #
    # /?...;...;...
    #
    # p = Project
    # a = Action like (
    #       blob,
    #       blob_plain,
    #       commitdiff,
    #       commit,
    #       history,
    #       log,
    #       rss|atom,
    #       shortlog,
    #       summary,
    #       tag,
    #       tree,
    #       snapshot
    #     )
    # h = SHA Hash
    # hb= SHA Hash Tree Base
    # f= file/dir
    # sf= snapshot format

    # Cgit uses the following:
    #
    # /project/action/?...
    #
    # action ( commit, log, diff, tree, tag, patch )
    #
    # id = SHA Hash
    # id2 = SHA Hash
    # h = head
    #
    # Translation rules
    #
    # Project is a straight redirect
