Sorry: I documented the commands using different directory names from
the ones I used, and managed to miss three of the changes.
Here's the (I think corrected and complete) list of commands for anyone
who still needs it:
~$ cp /var/cache/apt/archives/wine1.6_1.6~rc2-0ubuntu1~ppa1_amd64.deb
/tmp/
I've also modified the wine deb package, and am simply providing command
lines for anyone with less hacking confidence.
~$ cp /var/cache/apt/archives/wine1.6_1.6~rc2-0ubuntu1~ppa1_amd64.deb
/tmp/wine1.6_1.6~rc2-0ubuntu1~ppa1_amd64.deb
~$ cd /tmp
~$ mkdir wine-deb
~$ dpkg-deb -x wine1.6_1.6~rc2-0u
