.Nm patchdiff
.Nd compare sets of patches
.Sh SYNOPSIS
.Nm
.Op Fl d Ar output-directory
.Sh DESCRIPTION
.Nm
is a perl script that simplifies comparing a set of previously
existing patches with a new one created with
.Xr mkpatches 1 .

.Nm
must be called from the package's main directory, that is
$PKGSRC/category/program. For each patch existing in either the
patches or the $WRKDIR/.newpatches directory (the second of which can
be overridden by the argument of the
.Fl d
option), a matching patch is
looked for in the other directory, and, if one is found, the two are
compared with
.Xr diff 1 .
