Michael,

That little example is very cool and sure do appreciate you taking the time to help me out.  I got the source code and can take if from here. Thank-you very much.

I was curious as to where I might be able to find out what
non-command-line interfaces into .deb packages are available.  For
instance, is there a C interface that could pull out information such as
Name, Version, Release, etc... ?

libapt_inst (from the apt package) provides a interface in C++ and
python-apt (module apt_inst) provides a interface in python.

Attached is a example using python-apt.

Cheers,
