Sorry Chris, I had not seen your proposal. A little more background on why
I implemented such a complicated approach.
Debian's current packaging tacks a ".1" on the end of the SONAME. I *think*
this is necessary, but I'm not a Debian packaging expert; Sylvestre could
confirm. Anyway, that .1 doesn't make sense for everyone (anyone else?),
which is why it would be specified in an option.
