exchange: use context manager for locks and transaction in unbundle() Note that the transactionmanager doesn't actually create a transaction -- that is done the first time .transaction() is called on it (if at all). Consequently, .close() and .release() won't do anything if no transaction has been created. This makes it a little unusual, but it still works as a context manager.

Mercurial

Mercurial is a fast, easy to use, distributed revision control tool for software developers.

Basic install:

$ make            # see install targets
$ make install    # do a system-wide install
$ hg debuginstall # sanity-check setup
$ hg              # see help

Running without installing:

$ make local      # build for inplace usage
$ ./hg --version  # should show the latest version

See https://mercurial-scm.org/ for detailed installation instructions, platform-specific notes, and Mercurial user information.
