The upstream aptitude darcs repository is available from
<http://people.debian.org/~dburrows/darcs/aptitude>.  The Debian
packaging is maintained in a darcs branch, available from
<http://people.debian.org/~dburrows/darcs/aptitude-debian>.  Upstream
and Debian releases are tagged by their version numbers (e.g., "0.4.1"
and "0.4.1-1").


To easily build the Debian packaging from the darcs branch, you can
use darcs-build-assembly, available from the repository
<http://people.debian.org/~dburrows/darcs/darcs-build-assembly>; this
command should be run with the .orig.tar.gz file in the parent
directory (if no .orig.tar.gz file exists, one will be created
automatically; however, this will result in md5sum mismatches if you
try to upload to Debian).
