Bug#163225: apt: document that it will install over a locally-compiled package

[Raj Manandhar <raj@colsa.com>]

Package: apt
Version: 0.5.4
Severity: minor

If I download a source package, compile it, build a .deb, and install,
then run apt-get upgrade, apt decides that the local package is out of
date and will download the binary package and install it, overwriting
the local work. This happens even if the versions and Debian revisions
are the same for the local and downloaded binary packages. I guess
this must be happening because the md5sum of the local package doesn't
match what apt is expecting, so it thinks that there is something
wrong (note that there is no error message, though).

I think that an informative message should be printed in this
situation. Also, the behavior should be documented in the apt-get man
page or elsewhere (I couldn't find any mention of this anywhere except
for some musings on a security page about signing packages in a future
security infrastructure). I decided that the actual behavior of the
apt-get program is OK, once one realizes what is going on. I'm going
to try changing the Debian revision of the local package from 2 to
something like 2.1.
