-'git-merge-file' incorporates all changes that lead from the `<base-file>`
+'git merge-file' incorporates all changes that lead from the `<base-file>`

normally outputs a warning and brackets the conflict with lines containing
<<<<<<< and >>>>>>> markers. A typical conflict will look like this:

The exit value of this program is negative on error, and the number of
conflicts otherwise. If the merge was clean, the exit value is 0.

EXAMPLES
--------
Use the given merge strategy; can be supplied more than
once to specify them in the order they should be tried.
If there is no `-s` option, a built-in list of strategies
- is used instead ('git-merge-recursive' when merging a single
- head, 'git-merge-octopus' otherwise).
+ is used instead ('git merge-recursive' when merging a single
+ head, 'git merge-octopus' otherwise).
--summary::
--no-summary::
-v::
--verbose::
Be verbose.
+
+ -X <option>::
+ --strategy-option=<option>::
+ Pass merge strategy specific option through to the merge
+ strategy.
