The trouble with that scheme is we could easily come out with a new
ubuntu version that was alphabetically before dapper.  If the next
release were "chippy", for instance, the naming scheme would have to be
changed again to make the chippy package a later version than the dapper
one.

I just went exhaustively through the diff file, and it seems like a vast
majority of the changes to the wine source code itself were obsolete
cruft from about 2 years ago or worse.  There's even still mentions of
wine.conf in there, which hasn't been used for about 5 years now.  There
were quite a few changes in the debian package, but most of this was
just due to problems arising from the confusing splitting the debian
package does in the first place (against the advice of upstream.)

Sure I do - check out debian/wine.mime in the package, for instance.
Right-clicking an executable to run in Wine works just fine.

Ahh, I see what you mean.  I've made the changes in the new version.

The trouble with that approach is they don't smoothly upgrade from the
old split versions (in Debian or in Ubuntu Hoary).  Again, this is due
to a bug in apt-get (it looks at the current package's depends [wine on
libwine] rather than the package to be installed's depends [libwine on
wine]).


Any other thoughts?


Thanks again,
Scott Ritchie
