 It is possible to use bookmark names in every revision lookup (e.g. hg
 merge, hg update).
+
+The bookmark extension offers the possiblity to have a more git-like experience
+by adding the following configuration option to your .hgrc:
+
+[bookmarks]
+track.current = True
+
+This will cause bookmarks to track the bookmark that you are currently on, and
+just updates it. This is similar to git's approach of branching.

+'''Bugzilla integration
+
+This hook extension adds comments on bugs in Bugzilla when changesets
+that refer to bugs by Bugzilla ID are seen. The hook does not change bug
+status.
+
+The hook updates the Bugzilla database directly. Only Bugzilla installations
+using MySQL are supported.
+
+The hook relies on a Bugzilla script to send bug change notification emails.
+That script changes between Bugzilla versions; the 'processmail' script used
+prior to 2.18 is replaced in 2.18 and subsequent versions by
+'config/sendbugmail.pl'. Note that these will be run by Mercurial as the user
+pushing the change; you will need to ensure the Bugzilla install file
+permissions are set appropriately.
+
+Configuring the extension:
+
+    [bugzilla]
+    host       Hostname of the MySQL server holding the Bugzilla database.
+    db         Name of the Bugzilla database in MySQL. Default 'bugs'.
+    user       Username to use to access MySQL server. Default 'bugs'.
+    password   Password to use to access MySQL server.
+    timeout    Database connection timeout (seconds). Default 5.
+    version    Bugzilla version. Specify '3.0' for Bugzilla versions from
+               3.0 onwards, and '2.16' for versions prior to 3.0.
+    bzuser     Fallback Bugzilla user name to record comments with, if
+               changeset committer cannot be found as a Bugzilla user.
+    notify     The command to run to get Bugzilla to send bug change
+               notification emails. Substitutes one string parameter,
+               the bug ID. Default 'cd /var/www/html/bugzilla && '
+                                   './processmail %s nobody@nowhere.com'.
+    regexp     Regular expression to match bug IDs in changeset commit message.
+               Must contain one "()" group. The default expression matches
+               'Bug 1234', 'Bug no. 1234', 'Bug number 1234',
+               'Bugs 1234,5678', 'Bug 1234 and 5678' and variations thereof.
+               Matching is case insensitive.
+    style      The style file to use when formatting comments.
+    template   Template to use when formatting comments. Overrides
+               style if specified. In addition to the usual Mercurial
+               keywords, the extension specifies:
+                   {bug}       The Bugzilla bug ID.
+                   {root}      The full pathname of the Mercurial repository.
+                   {webroot}   Stripped pathname of the Mercurial repository.
+                   {hgweb}     Base URL for browsing Mercurial repositories.
+               Default 'changeset {node|short} in repo {root} refers '
+                       'to bug {bug}.\\ndetails:\\n\\t{desc|tabindent}'
+    strip      The number of slashes to strip from the front of {root}
+               to produce {webroot}. Default 0.
+    usermap    Path of file containing Mercurial committer ID to Bugzilla user
+               ID mappings. If specified, the file should contain one mapping
+               per line, "committer"="Bugzilla user". See also the
+               [usermap] section.
+
+    [usermap]
+    Any entries in this section specify mappings of Mercurial committer ID
+    to Bugzilla user ID. See also [bugzilla].usermap.
+    "committer"="Bugzilla user"
+
+    [web]
+    baseurl    Base URL for browsing Mercurial repositories. Reference from
+               templates as {hgweb}.
+
+Activating the extension:
+
+    [extensions]
+    hgext.bugzilla =
+
+    [hooks]
+    # run bugzilla hook on every change pulled or pushed in here
+    incoming.bugzilla = python:hgext.bugzilla.hook
