Can it handle the rebuild for multiple architectures?
And can one provide a log message associated with each patch?

FYI, I currently use a script (one for each source package)
based on common functions (attached).

A typical script consists of:

------------------------------------------------------------
#!/usr/bin/env zsh

set -e

. $0:h/mkdebs-functions

apt-get source -t unstable <package_name>

cd <package_name>-*

[patch code]

dch -l +local "<log message>"

md_build "$@"
------------------------------------------------------------

Note that mkdebs-functions does the cd to a temporary directory.

If I wish to add another patch before the rebuild, I can insert:

[patch code 2]
dch -a "<log message 2>"

If I wish to add another patch after a rebuild (so that I need
to increase the local version):

[patch code 2]
dch -l +local "<log message 2>"
