I am fully aware of how apt and dpkg are supposed to work - I cannot
ship a precompiled deb for legal reasons, so either each user builds
and installs it manually, or I try to help them.
Installing this package pops up a debhelper choice of which packages
they want to build and install. I suppose I am closest to m-a in how
it is working.
I would rather that this package pops up a menu each time it is
reinstalled as it means users have some way of knowing a new upstream
package is available should they wish to build and install it.
I am also fully aware of how nasty this is, however I am tied by legal
requirements with this package that each user has to download it
themselves so the download is tracked.
Trying to help, I came up with a script that can build and install the
package, and I would like to put this script in a deb, and have it
autorun so that we can make other packages depend on this one such
that a user has a chance of getting the package built and installed
easily
