+=================

+NAME
+----
+git-merge-file - Run a three-way file merge
+
+
+SYNOPSIS
+--------
+[verse]
+'git merge-file' [-L <current-name> [-L <base-name> [-L <other-name>]]]
+	[--ours|--theirs|--union] [-p|--stdout] [-q|--quiet] [--marker-size=<n>]
+	<current-file> <base-file> <other-file>
+
+
+DESCRIPTION
+-----------
+'git merge-file' incorporates all changes that lead from the `<base-file>`
+to `<other-file>` into `<current-file>`. The result ordinarily goes into
+`<current-file>`. 'git merge-file' is useful for combining separate changes
+to an original. Suppose `<base-file>` is the original, and both
+`<current-file>` and `<other-file>` are modifications of `<base-file>`,
+then 'git merge-file' combines both changes.
+
+A conflict occurs if both `<current-file>` and `<other-file>` have changes
+in a common segment of lines. If a conflict is found, 'git merge-file'
+normally outputs a warning and brackets the conflict with lines containing
+<<<<<<< and >>>>>>> markers. A typical conflict will look like this:
+
+	<<<<<<< A
+	lines in file A
+	=======
+	lines in file B
+	>>>>>>> B
+
+If there are conflicts, the user should edit the result and delete one of
+the alternatives.  When `--ours`, `--theirs`, or `--union` option is in effect,
+however, these conflicts are resolved favouring lines from `<current-file>`,
+lines from `<other-file>`, or lines from both respectively.  The length of the
+conflict markers can be given with the `--marker-size` option.
+
+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.
+
+'git merge-file' is designed to be a minimal clone of RCS 'merge'; that is, it
+implements all of RCS 'merge''s functionality which is needed by
+linkgit:git[1].
+
+
+OPTIONS
+-------
+
+-L <label>::
+	This option may be given up to three times, and
+	specifies labels to be used in place of the
+	corresponding file names in conflict reports. That is,
+	`git merge-file -L x -L y -L z a b c` generates output that
+	looks like it came from files x, y and z instead of
+	from files a, b and c.
+
+-p::
+	Send results to standard output instead of overwriting
+	`<current-file>`.
+
+-q::
+	Quiet; do not warn about conflicts.
+
+--ours::
+--theirs::
+--union::
+	Instead of leaving conflicts in the file, resolve conflicts
+	favouring our (or their or both) side of the lines.
+
+
+EXAMPLES
+--------
+
+`git merge-file README.my README README.upstream`::
+
+	combines the changes of README.my and README.upstream since README,
+	tries to merge them and writes the result into README.my.
+
+`git merge-file -L a -L b -L c tmp/a123 tmp/b234 tmp/c345`::
+
+	merges tmp/a123 and tmp/c345 with the base tmp/b234, but uses labels
+	`a` and `c` instead of `tmp/a123` and `tmp/c345`.
