+.SH NAME
+debdiff-apply \- apply a debdiff to a Debian source package
+
+.SH SYNOPSIS
+.B debdiff-apply
+[options] [orig_dsc_or_dir] [patch_file]
+.br
+.B debdiff-apply
+[options] < [patch_file]
+
+.SH DESCRIPTION
+.B debdiff-apply
+takes a \fIpatchfile\fR that describes the differences between two Debian
+source packages \fIold\fR and \fInew\fR, and applies it to a target Debian
+source package \fIorig\fR.
+.PP
+\fIorig\fR could either be the same as \fIold\fR or it could be different.
+\fIpatchfile\fR is expected to be a unified diff between two Debian source
+trees, as what
+.BR debdiff (1)
+normally generates.
+.PP
+Any changes to \fIdebian/changelog\fR are dealt with specially, to avoid the
+conflicts that changelog diffs typically produce when applied naively. The
+exact behaviour may be tweaked in the future, so one should not rely on it.
+.PP
+If \fIpatchfile\fR does not apply to \fIorig\fR, even after the special-casing
+of \fIdebian/changelog\fR, no changes are made and
+.BR debdiff-apply (1)
+will exit with a non-zero error code.
+
+.SH ARGUMENTS
+.TP
+orig_dsc_or_dir
+Target to apply the patch to. This can either be an unpacked source tree, or a
+\[char46]dsc file. In the former case, the directory is modified in\-place; in
+the latter case, a second .dsc is created. Default: \fI.\fP
+.TP
+patch_file
+Patch file to apply, in the format output by
+.BR debdiff (1).
+Default:
+\fI\,/dev/stdin\/\fP
+
+.SH OPTIONS

+.TP
+\fB\-c\fR CHANGELOG, \fB\-\-changelog\fR CHANGELOG

+.TP
+\fB\-\-source\-version\fR
+Don't apply the patch; instead print out the version of the package that it is
+supposed to be applied to, or nothing if the patch does not specify a source
+version.
+.TP
+\fB\-\-target\-version\fR
+Don't apply the patch; instead print out the new version of the package
+.BR debdiff-apply (1)
+would generate, when the patch is applied to the the given target
+package, as specified by the other arguments.
+.SS "For .dsc patch targets:"
+.TP
+\fB\-\-no\-clean\fR
+Don't clean temporary directories after a failure, so you can examine what
+failed.
+.TP
+\fB\-\-quilt\-refresh\fR
