SYNOPSIS
--------
-'git-patch-id' [ --option ] <args>...
+'git-patch-id' < <patch>
DESCRIPTION
-----------
-Does something not yet documented.
+A "patch ID" is nothing but a SHA1 of the diff associated with a patch, with
+whitespace and line numbers ignored. As such, it's "reasonably stable", but at
+the same time also reasonably unique, ie two patches that have the same "patch
+ID" are almost guaranteed to be the same thing.
+IOW, you can use this thing to look for likely duplicate commits.
