-       "@code{Patches} is a patch-tracking tool initially written for the QEMU
-project.  It provides commands that build a database of patches from a mailing
-list, and commands that can search that database.  It allows users to track
-the status of a patch, apply patches, and search for patches---all that from
-the command-line or from Emacs via its Notmuch integration.")
