dpkg >= 1.14.6 supports the use of a "Homepage:" field in debian/control. This should replace the Homepage pseudo-field in extended descriptions.
Transition plan
1.A Implement support in APT frontends and libraries:
libapt: done
Adept Manager: 445649 - Can be ignored as Adept is not anymore in testing for now.
aptitude: done
synaptic: 445636
kpackage: done
packages.debian.org: done
1.B Adapt developer documentation such as the Developer's Reference:
Developer's Reference: 445642 (pending)
1.C Add Homepage field to dh-make templates. 445678 (pending in the package SVN repository)
2. Make lintian stop issuing "I: unknown-field-in-control homepage". done
3. Make linda and lintian issue a warning to packages including a homepage in their extended description.
lintian: done
linda: 445673
3a. Document Homepage field usage in Wiki Page ["HomepageFieldHOWTO"]. done
3b. Start advertizing the field. [http://lists.debian.org/debian-devel-announce/2007/11/msg00006.html Done by Raphaƫl Hertzog in debian-devel-announce]. done
4. Add Homepage to Debian Policy Manual: 452105
5. After some time, announce mass wishlist bug filing on debian-devel-announce. Stefano Zacchiroli has setup [http://upsilon.cc/~zack/stuff/homepage-field/ A page with counters] showing packages using the old pseudo-field and not the new one as well as packages using the new one.
6. After some time, proceed to mass wishlist bug filing.
7. After even more time, change the policy manual to should
8. file yet another round of bugs, now non-wishlist.
