-.. _hg-commit:
-
-How do I commit a change to a file?
-'''''''''''''''''''''''''''''''''''
-
-To commit any changes to a file (which includes adding a new file or deleting
-an existing one), you use the command::
-
- hg commit [PATH]
-
-``PATH`` is optional: if it is omitted, all changes in your working copy
-will be committed to the local repository.  When you commit, be sure that all
-changes are desired by reviewing them first; also, when making commits that you
-intend to push to public repositories, you should **not** commit together
-unrelated changes.
-
-To abort a commit that you are in the middle of, leave the message
-empty (i.e., close the text editor without adding any text for the
-message).  Mercurial will then abort the commit operation so that you can
-try again later.
-
-Once a change is committed to your local repository, it is still only visible
-by you.  This means you are free to experiment with as many local commits
-you feel like.
-
-.. note::
-   If you do not like the default text editor Mercurial uses for
-   entering commit messages, you may specify a different editor,
-   either by changing the ``EDITOR`` environment variable or by setting
-   a Mercurial-specific editor in your global ``.hgrc`` with the ``editor``
-   option in the ``[ui]`` section.
-
-
-.. _hg-merge-conflicts:
-
-How do I solve merge conflicts?
-'''''''''''''''''''''''''''''''
-
-The easiest way is to install KDiff3 --- Mercurial will open it automatically
-in case of conflicts, and you can then use it to solve the conflicts and
-save the resulting file(s).  KDiff3 will also take care of marking the
-conflicts as resolved.
-
-If you don't use a merge tool, you can use ``hg resolve --list`` to list the
-conflicting files, resolve the conflicts manually, and the use
-``hg resolve --mark <file path>`` to mark these conflicts as resolved.
-You can also use ``hg resolve -am`` to mark all the conflicts as resolved.
-
-.. note::
-   Mercurial will use KDiff3 automatically if it's installed and it can find
-   it --- you don't need to change any settings.  KDiff3 is also already
-   included in the installer of TortoiseHg.  For more information, see
-   https://www.mercurial-scm.org/wiki/KDiff3.
-
-
-.. _hg-null-merge:
-
-How do I make a null merge?
-'''''''''''''''''''''''''''
-
-If you committed something (e.g. on 3.5) that shouldn't be ported on newer
-branches (e.g. on default), you have to do a *null merge*::
-
-   cd 3.x
-   hg merge 3.5
-   hg revert -ar default
-   hg resolve -am  # needed only if the merge created conflicts
-   hg ci -m '#12345: null merge with 3.5.'
-
-Before committing, ``hg status`` should list all the merged files as ``M``,
-but ``hg diff`` should produce no output.  This will record the merge without
-actually changing the content of the files.
-
-
-.. _hg-heads-merge:
-
-I got "abort: push creates new remote heads!" while pushing, what do I do?
-''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''
-
-If you see this message while pushing, it means that you committed something
-on a clone that was not up to date, thus creating a new head.
-This usually happens for two reasons:
-
-1. You forgot to run ``hg pull`` and/or ``hg up`` before committing;
-2. Someone else pushed on the main repo just before you, causing a push race;
-
-First of all you should pull the new changesets using ``hg pull``.  Then you can
-use ``hg heads`` to see which branches have multiple heads.
-
-If only one branch has multiple heads, you can do::
-
-   cd default
-   hg heads .
-   hg up csid-of-the-other-head
-   hg merge
-   hg ci -m 'Merge heads.'
-
-``hg heads .``  will show you the two heads of the current branch: the one you
-pulled and the one you created with your commit (you can also specify a branch
-with ``hg heads <branch>``).  While not strictly necessary, it is highly
-recommended to switch to the other head before merging.  This way you will be
-merging only your changeset with the rest, and in case of conflicts it will be
-a lot easier.
-
-If more than one branch has multiple heads, you have to repeat these steps for
-each branch.  Since this creates new changesets, you will also have to
-:ref:`merge them between branches <branch-merge>`.  For example, if both ``3.5``
-and ``default`` have multiple heads, you should first merge heads in ``3.5``,
-then merge heads in ``default``, and finally merge ``3.5`` with ``default``
-using ``hg merge 3.5`` as usual.
-
-In order to avoid this, you should *always remember to pull and update before
-committing*.
-
-
-How do I undo the changes made in a recent commit?
-''''''''''''''''''''''''''''''''''''''''''''''''''
-
-First, this should not happen if you take the habit of reviewing changes before
-committing them.
-
-In any case, run::
-
- git revert <revision number>
-
-This will modify your working copy so that all changes in ``<revision number>``
-(including added or deleted files) are undone.  You then need to commit
-these changes so that the backout gets permanently recorded.
