What's up with the libqtrpc2-1 / rds package in the archives?

I am considering using libqtrpc2-1 in my application but there seems to be some confusion over the name of the package.

On the right-hand side of the package page, we see:

So it looks like the package is named "rds".

...or is it? Attempting to view the copyright file results in a 404. The changelog file however, loads fine. The link for bug reports contains "rds" in the URL.

It gets worse - the -devel package contains a directory in /usr/include that is named qtrpc2 not rds. This is confusing to say the least.

So what is the name of this package? And what's going on?

The libqtrpc2-1 binary package is built from the rds source package, as is listed on Launchpad It's quite common for source packages to build a number of binary packages, some of which may not appear to have a related name.
