Russ has a similar script[0]. There's definite overlap between the two.
I wonder if we can consolidate some of the functionality of these into a
common script and include that.

I like that backport-dsc simply prepares the source package and then
leaves the building up to the user's workflow.
Cheers,

+.TH BACKPORT-DSC "1" "February 2012" "DEBIAN" "User Commands"
+.SH NAME
+backport-dsc \- backport Debian source packages
+.SH SYNOPSIS
+.B backport-dsc
+[\fIOPTIONS\fR] \fI<dsc-file>\fR
+.SH DESCRIPTION
+Helper to aid backporting a Debian source package to an arbitrary distribution
+release.
+.PP
+backport\-dsc aids backporting by appropriately mangling the source package
+version, adjusting the maintainer of a package and compiling an informative
+changelog entry. Moreover, it supports distribution specific patches (plain, or
+for format 3.0 (quilt) source packages) and allow modification of debian/control
+via arbitrary 'sed' expressions.
+.PP
+Backport relevant patches can be embedded in source packages for use with
+backport\-dsc. The distribution name (see \fB\-\-target\-distribution\fR) serves as an
+identifier to search for patches in the source package that shall be applied
+for a particular distribution. For packages using format the 3.0 (quilt),
+backport\-dsc will look for debian/patches/series\-<distname> and append it to
+the main patch series. Moreover, backport\-dsc will also look for patches
+matching /debian/patches/<distname>\-dsc\-patch* and apply them to the source
+package. The latter patches, unlike the former quilt series, can also be used
+to modify the debian/ directory itself.
+.SH OPTIONS
+
+\fB\-d\fR <distname>, \fB\-\-target\-distribution\fR <distname>
+.IP
+Arbitrary distribution name (e.g. squeeze\-backports). This will be the target
+distribution used for the backport changelog entry. The distribution name
+also serves as an identifier to search for backport patches in the source
+package.
+.PP
+\fB\-h\fR, \fB\-\-help\fR
+.IP
+Print short description, usage summary and option list.
+.PP
+\fB\-\-maint\-email\fR <email>
+.IP
+Specify the backport maintainer's email address. Alternatively, backport\-dsc
+will use the DEBEMAIL environment setting.
+.PP
+\fB\-\-maint\-name\fR <name>
+.IP
+Specify the backport maintainer's real name. Alternatively, backport\-dsc will
+use the DEBFULLNAME environment setting.
+.PP
+\fB\-\-mod\-control\fR <expression>
+.IP
+sed expression to modify debian/control. The option can be given multiple
+times and all expressions will be passed to sed in the order of appearance.
+This can be used to, e.g. change build or runtime dependencies.
+.PP
+\fB\-\-no\-backport\-patches\fR
+.IP
+If set, potentially existing backport patches will not be applied/activated.
+.PP
+\fB\-\-no\-colored\fR
+.IP
+If set, backport\-dsc won't colorize its status and error messages.
+.PP
+\fB\-\-no\-maintainer\-update\fR
+.IP
+If set, the orginal maintainer is preserved in the backported source package.
+This should only be done if original maintainer and backporter are identical.
+Otherwise the porter should take responsibility for the source package
+backport and identify herself as the maintainer.
+.PP
+\fB\-s\fR <string>, \fB\-\-version\-suffix\fR <string>
+.IP
+Version suffix that will be appended to the original source package version,
+ideally indicating the backport target distribution. The resulting package
+version will follow this schema:
+.IP
+<originalversion><prefix><suffix>+<digit>
+.IP
+e.g.: 1.2.3\-4~bpo60+1 with default <prefix>=~
+.PP
+\fB\-p\fR <string>, \fB\-\-version\-prefix\fR <string>
+.IP
+Version prefix that will be prepended to the backport version.
+By default it is ~ but want to be changed (e.g. to +) for forward\-porting to
+next releases.
+.PP
+\fB\-\-verbose\fR
+.IP
+Enable additional status messages.
+.PP
+\fB\-\-verbose\-help\fR
+.IP
+Print all available help.
+.PP
+\fB\-\-version\fR
+.IP
+Print version information and exit.
+.SH ENVIRONMENT
+
+backport\-dsc acknowledges the common environment variables DEBFULLNAME and
+DEBEMAIL to specify the maintainer. Moreover the following variables can be
+used to customize backport\-dsc (each shown with an example):
+.PP
+BACKPORTDSC_DISTRIBUTION="squeeze\-backports"
