 '''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, the largefiles for the changeset will by default not be
 pulled down. 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). One way to pull largefiles
 when pulling is thus to use --update, which will update your working
 copy to the latest pulled revision (and thereby downloading any new
 largefiles).
 
 If you want to pull largefiles you don't need for update yet, then
 you can use pull with the `--lfrev` option or the :hg:`lfpull` command.
 
-If you know you are pulling from a non-default location and want do
-download all the largefiles that corresponds to the new changesets at
+If you know you are pulling from a non-default location and want to
+download all the largefiles that correspond to the new changesets at
 the same time, then you can pull with `--lfrev "pulled()"`.
 
 If you just want to ensure that you will have the largefiles needed to
 merge or rebase with new heads that you are pulling, then you can pull
 with `--lfrev "head(pulled())"` flag to pre-emptively download any largefiles
 that are new in the heads you are pulling.
 
 Keep in mind that network access may now be required to update to
 changesets that you have not previously updated to. The nature of the
 largefiles extension means that updating is no longer guaranteed to
 be a local-only operation.
 
 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
 threshold, set ``largefiles.minsize`` 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]
   minsize = 2
 
   $ 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.
 
 The ``largefiles.minsize`` and ``largefiles.patterns`` config options
 will be ignored for any repositories not already containing a
 largefile. To add the first largefile to a repository, you must
 explicitly do so with the --large flag passed to the :hg:`add`
 command.
