-.Sh NAME
-.Nm diffburst
-.Nd split recursive diff output into separate files
-.Sh SYNOPSIS
-.Nm diffburst < input
-.Sh DESCRIPTION
-.Nm
-reads the output of a recursive diff from standard input,
-and writes it back out as a series of patchfiles, where each patchfile
-contains the diff for a single file. The files are named
-patch-aa, patch-ab, and so on.
-.Pp
-This program is intended to aid in developing
-.Fx
-ports,
-where the 'one patchfile per file' rule applies.
