DESCRIPTION
-----------
-Prepare each commit between <since> and <until> with its patch in
+Prepare each commit with its patch in
one file per commit, formatted to resemble UNIX mailbox format.
-If ..<until> is not specified, the head of the current working
-tree is implied. For a more complete list of ways to spell
-<since> and <until>, see "SPECIFYING REVISIONS" section in
-gitlink:git-rev-parse[1].
-
The output of this command is convenient for e-mail submission or
for use with gitlink:git-am[1].
+There are two ways to specify which commits to operate on.
+
+1. A single commit, <since>, specifies that the commits leading
+ to the tip of the current branch that are not in the history
+ that leads to the <since> to be output.
+
+2. Generic <revision range> expression (see "SPECIFYING
+ REVISIONS" section in gitlink:git-rev-parse[1]) means the
+ commits in the specified range. A single commit, when
+ interpreted as a <revision range> expression, means
+ "everything that leads to that commit", but that is taken as
+ the special case above. If you want to format everything
+ since project inception to one commit, say "git format-patch
+ \--root <that-commit>", as showing the root commit as patch
+ requires \--root option anyway.
+
By default, each output file is numbered sequentially from 1, and uses the
first line of the commit message (massaged for pathname safety) as
the filename. With the --numbered-files option, the output file names
not in the origin branch. For each commit a separate file
is created in the current directory.
+git-format-patch \--root origin::
+ Extract all commits which that leads to 'origin' since the
+ inception of the project.
+
git-format-patch -M -B origin::
The same as the previous one. Additionally, it detects
and handles renames and complete rewrites intelligently to
