Note To check out earlier revisions, you should use hgupdateREV. To cancel an uncommitted merge (and
lose your changes), use hgmerge--abort.
With no revision specified, revert the specified files or directories to the contents they had in the
parent of the working directory. This restores the contents of files to an unmodified state and
unschedules adds, removes, copies, and renames. If the working directory has two parents, you must
explicitly specify a revision.
Using the -r/--rev or -d/--date options, revert the given files or directories to their states as of a
specific revision. Because revert does not change the working directory parents, this will cause these
files to appear modified. This can be helpful to "back out" some or all of an earlier change. See hgbackout for a related method.
Modified files are saved with a .orig suffix before reverting. To disable these backups, use
--no-backup. It is possible to store the backup files in a custom directory relative to the root of the
repository by setting the ui.origbackuppath configuration option.
See hghelpdates for a list of formats valid for -d/--date.
See hghelpbackout for a way to reverse the effect of an earlier changeset.
Returns 0 on success.
