Gitolite update

This is an update on gitolite, an ssh-based access control tool for using git in a typical corporate environment. The latest version is always at git://github.com/sitaramc/gitolite.git

While still remaining upward compatible with the "inspiration" project (gitosis), the extra features now form the largest section in http://github.com/sitaramc/gitolite/blob/pu/doc/3-faq-tips-etc.mkd. This was mostly the result of users asking for features they wanted, so please take a look to see if something there strikes your fancy.

    [However, the 2 programs that do the actual access control *still*
    total only about 90 lines; I firmly intend to keep those less than
    100 to make them easy to audit for security.]

Significant additions since the last update -------------------------------------------

Installs/upgrades

  * The easy install script is also good for upgrades.  The new "-q"
    option is particularly useful, and makes an upgrade really quick and
    "one command".

    Remote admin mode (where you make config changes in a clone of the
    gitolite-admin repo, and push them to the server) is now the
    *default*.  I think I managed to put enough ssh intelligence into
    the ssh aspect to make this finally work without pain, and people on
    #git have said it does work (i.e., it's not just me claiming it ;-)

Config file maintenance

  * Large config files (when you have many, many, repos) can be split up
    and delegated to different people.  The main config file can give a
    specific user the authority to manage a specific group of repos, and
    that user can then maintain the access control for those repos
    independently.

  * Config files are also checked for mismatches in pubkeys and
    usernames, which is good for catching typos early.

Documentation etc

  * The documentation, help text, and messages that come out have had
    numerous changes based on user feedback on #git.  Like in the easy
    install script, a lot of effort has gone into the ssh aspect.

Other (minor) updates ---------------------

  * Supports git installed outside the normal $PATH (on the server).
    Without this, *all* your users would have to specify the upload-pack
    and receive-pack program paths, either by setting config variables
    or using "-u", "--exec" etc. in the clone/push commands.

  * Trying a plain ssh to your gitolite account now tells you what repos
    you have access to, instead of a (largely useless) error message
    about needing SSH_ORIGINAL_COMMAND.  This sounds like a gimmick...
    until you actually need it :)

  * I've finally started tagging releases, and now an install or an
    upgrade done from a clone will record the version number.  When you
    upgrade, it tells you you're upgrading from version foo to version
    bar.

  * When specifying repos in subdirectories (foo/bar/baz.git) you no
    longer have to manually create foo/bar on the server first.

Recap of older features (for completeness) ------------------------------------------

  * per-branch permissions, including fine-grained control over "rewind"
  * install without root access on any Unix
  * simpler but much more powerful config file syntax
  * more comprehensive logging
  * "personal" namespace prefix for each user
  * "deny" rights in the config file (in the "rebel" branch)

Questions and support ---------------------

I'm often on #git, subject to my living in UTC+0530 time, and email is also welcome (sitaramc@gmail.com is preferred, but sitaram.chamarty@tcs.com may get my attention quicker). If you log an issue on github, please also send an email; I am checking github more often now (having missed two issues for many days) but it's not as frequent as I would have liked.
