+'''track large binary files
+
+Large binary files tend to be not very compressible, not very
+diffable, and not at all mergeable. Such files are not handled
+efficiently by Mercurial's storage format (revlog), which is based on
+compressed binary deltas; storing large binary files as regular
+Mercurial files wastes bandwidth and disk space and increases
+Mercurial's memory usage. The largefiles extension addresses these
+problems by adding a centralized client-server layer on top of
+Mercurial: largefiles live in a *central store* out on the network
+somewhere, and you only fetch the revisions that you need when you
+need them.
+
+largefiles works by maintaining a "standin file" in .hglf/ for each
+largefile. The standins are small (41 bytes: an SHA-1 hash plus
+newline) and are tracked by Mercurial. Largefile revisions are
+identified by the SHA-1 hash of their contents, which is written to
+the standin. largefiles uses that revision ID to get/put largefile
+revisions from/to the central store. This saves both disk space and
+bandwidth, since you don't need to retrieve all historical revisions
+of large files when you clone or pull.
+
+To start a new repository or add new large binary files, just add
+--large to your ``hg add`` command. For example::
+
+  $ dd if=/dev/urandom of=randomdata count=2000
+  $ hg add --large randomdata
+  $ hg commit -m 'add randomdata as a largefile'
+
+When you push a changeset that adds/modifies largefiles to a remote
+repository, its largefile revisions will be uploaded along with it.
+Note that the remote Mercurial must also have the largefiles extension
+enabled for this to work.
+
+When you pull a changeset that affects largefiles from a remote
+repository, Mercurial behaves as normal. However, when you update to
+such a revision, any largefiles needed by that revision are downloaded
+and cached (if they have never been downloaded before). This means
+that network access may be required to update to changesets you have
+not previously updated to.
+
+If you already have large files tracked by Mercurial without the
+largefiles extension, you will need to convert your repository in
+order to benefit from largefiles. This is done with the 'hg lfconvert'
+command::
+
+  $ hg lfconvert --size 10 oldrepo newrepo
+
+In repositories that already have largefiles in them, any new file
+over 10MB will automatically be added as a largefile. To change this
+threshhold, set ``largefiles.size`` in your Mercurial config file to
+the minimum size in megabytes to track as a largefile, or use the
+--lfsize option to the add command (also in megabytes)::
+
+  [largefiles]
+  size = 2           XXX wouldn't minsize be a better name?
+
+  $ hg add --lfsize 2
+
+The ``largefiles.patterns`` config option allows you to specify a list
+of filename patterns (see ``hg help patterns``) that should always be
+tracked as largefiles::
+
+  [largefiles]
+  patterns =
+    *.jpg
+    re:.*\.(png|bmp)$
+    library.zip
+    content/audio/*
+
+Files that match one of these patterns will be added as largefiles
+regardless of their size.

+= largefiles - manage large binary files =
+This extension is based off of Greg Ward's bfiles extension which can be found
+at http://mercurial.selenic.com/wiki/BfilesExtension.
+
+== The largefile store ==
+
+largefile stores are, in the typical use case, centralized servers that have
+every past revision of a given binary file.  Each largefile is identified by
+its sha1 hash, and all interactions with the store take one of the following
+forms.
+
+-Download a bfile with this hash
+-Upload a bfile with this hash
+-Check if the store has a bfile with this hash
+
+largefiles stores can take one of two forms:
+
+-Directories on a network file share
+-Mercurial wireproto servers, either via ssh or http (hgweb)
+
+== The Local Repository ==
+
+The local repository has a largefile cache in .hg/largefiles which holds a
+subset of the largefiles needed. On a clone only the largefiles at tip are
+downloaded. When largefiles are downloaded from the central store, a copy is
+saved in this store.
+
+== The Global Cache ==
+
+largefiles in a local repository cache are hardlinked to files in the global
+cache. Before a file is downloaded we check if it is in the global cache.
+
+== Implementation Details ==
+
+Each largefile has a standin which is in .hglf. The standin is tracked by
+Mercurial.  The standin contains the SHA1 hash of the largefile. When a
+largefile is added/removed/copied/renamed/etc the same operation is applied to
+the standin. Thus the history of the standin is the history of the largefile.
+
+For performance reasons, the contents of a standin are only updated before a
+commit.  Standins are added/removed/copied/renamed from add/remove/copy/rename
+Mercurial commands but their contents will not be updated. The contents of a
+standin will always be the hash of the largefile as of the last commit. To
+support some commands (revert) some standins are temporarily updated but will
+be changed back after the command is finished.
+
+A Mercurial dirstate object tracks the state of the largefiles. The dirstate
+uses the last modified time and current size to detect if a file has changed
+(without reading the entire contents of the file).

+Largefiles allows for tracking large, incompressible binary files in Mercurial
+without requiring excessive bandwidth for clones and pulls.  Files added as
+largefiles are not tracked directly by Mercurial; rather, their revisions are
+identified by a checksum, and Mercurial tracks these checksums.  This way, when
+you clone a repository or pull in changesets, the large files in older
+revisions of the repository are not needed, and only the ones needed to update
+to the current version are downloaded.  This saves both disk space and
+bandwidth.
+
+If you are starting a new repository or adding new large binary files, using
+largefiles for them is as easy as adding '--large' to your hg add command.  For
+example:
+
+$ dd if=/dev/urandom of=thisfileislarge count=2000
+$ hg add --large thisfileislarge
+$ hg commit -m 'add thisfileislarge, which is large, as a largefile'
+
+When you push a changeset that affects largefiles to a remote repository, its
+largefile revisions will be uploaded along with it.  Note that the remote
+Mercurial must also have the largefiles extension enabled for this to work.
+
+When you pull a changeset that affects largefiles from a remote repository,
+nothing different from Mercurial's normal behavior happens.  However, when you
+update to such a revision, any largefiles needed by that revision are
+downloaded and cached if they have never been downloaded before.  This means
+that network access is required to update to revision you have not yet updated
+to.
+
+If you already have large files tracked by Mercurial without the largefiles
+extension, you will need to convert your repository in order to benefit from
+largefiles.  This is done with the 'hg lfconvert' command:
+
+$ hg lfconvert --size 10 oldrepo newrepo
+
+By default, in repositories that already have largefiles in them, any new file
+over 10MB will automatically be added as largefiles.  To change this
+threshhold, set [largefiles].size in your Mercurial config file to the minimum
+size in megabytes to track as a largefile, or use the --lfsize option to the
+add command (also in megabytes):
+
+[largefiles]
+size = 2
+
+$ hg add --lfsize 2
+
+The [largefiles].patterns config option allows you to specify specific
+space-separated filename patterns (in shell glob syntax) that should always be
+tracked as largefiles:
+
+[largefiles]

+First, enable the extension as explained in :hg:`help extensions`, and
+register the hook you want to run. ``incoming`` and ``outgoing`` hooks

+the sender::
 
   [hooks]
   # one email for each incoming changeset
   incoming.notify = python:hgext.notify.hook
-  # batch emails when many changesets incoming at one time
+  # one email for all incoming changesets

-The notify config file has same format as a regular hgrc file. It has
-two sections so you can express subscriptions in whatever way is
-handier for you.
-
-::
+Now the hooks are running, subscribers must be assigned to
+repositories. Use the ``[usersubs]`` section to map repositories to a
+given email or the ``[reposubs]`` section to map emails to a single
+repository::

-  # key is subscriber email, value is ","-separated list of glob patterns
+  # key is subscriber email, value is a comma-separated list of glob
+  # patterns

   [reposubs]
-  # key is glob pattern, value is ","-separated list of subscriber emails
+  # key is glob pattern, value is a comma-separated list of subscriber
+  # emails
   pattern = user@host
 
-Glob patterns are matched against path to repository root.
+Glob patterns are matched against absolute path to repository
+root. The subscriptions can be defined in their own file and
+referenced with::
+
+  [notify]
+  config = /path/to/subscriptionsfile
+
+Alternatively, they can be added to Mercurial configuration files by
+setting the previous entry to an empty value.
+
+At this point, notifications should be generated but will not be sent until you
+set the ``notify.test`` entry to ``False``.
+
+Notifications content can be tweaked with the following configuration entries:
+
+notify.test
+  If ``True``, print messages to stdout instead of sending them. Default: True.
+
+notify.sources
+  Space separated list of change sources. Notifications are sent only
+  if it includes the incoming or outgoing changes source. Incoming
+  sources can be ``serve`` for changes coming from http or ssh,
+  ``pull`` for pulled changes, ``unbundle`` for changes added by
+  :hg:`unbundle` or ``push`` for changes being pushed
+  locally. Outgoing sources are the same except for ``unbundle`` which
+  is replaced by ``bundle``. Default: serve.
+
+notify.strip
+  Number of leading slashes to strip from url paths. By default, notifications
+  references repositories with their absolute path. ``notify.strip`` let you
+  turn them into relative paths. For example, ``notify.strip=3`` will change
+  ``/long/path/repository`` into ``repository``. Default: 0.
+
+notify.domain
+  If subscribers emails or the from email have no domain set, complete them
+  with this value.
 
-If you like, you can put notify config file in repository that users
-can push changes to, they can manage their own subscriptions.
+notify.style
+  Style file to use when formatting emails.
+
+notify.template
+  Template to use when formatting emails.
+
+notify.incoming
+  Template to use when run as incoming hook, override ``notify.template``.
+
+notify.outgoing
+  Template to use when run as outgoing hook, override ``notify.template``.
+
+notify.changegroup
+  Template to use when running as changegroup hook, override
+  ``notify.template``.
+
+notify.maxdiff
+  Maximum number of diff lines to include in notification email. Set to 0
+  to disable the diff, -1 to include all of it. Default: 300.
+
+notify.maxsubject
+  Maximum number of characters in emails subject line. Default: 67.
+
+notify.diffstat
+  Set to True to include a diffstat before diff content. Default: True.
+
+notify.merge
+  If True, send notifications for merge changesets. Default: True.
+
+If set, the following entries will also be used to customize the notifications:
+
+email.from
+  Email ``From`` address to use if none can be found in generated email content.
+
+web.baseurl
+  Root repository browsing URL to combine with repository paths when making
+  references. See also ``notify.strip``.
