"""restore files to their checkout state
.. note::
- This command is most likely not what you are looking for.
- Revert will partially overwrite content in the working
- directory without changing the working directory parents. Use
- :hg:`update -r rev` to check out earlier revisions, or
- :hg:`update --clean .` to undo a merge which has added another
- parent.
+ To check out earlier revisions, you should use :hg:`update REV`.
+ To cancel a merge (and lose your changes), use :hg:`update --clean .`.
With no revision specified, revert the named files or directories
to the contents they had in the parent of the working directory.
