Simply add the following lines to your /etc/apt/sources.list.
If you are more used to synaptic, take a look here Adding other repositories.
Note that each line to be added is an APT line.
You can see the available packages here


deb http://babel.ls.fi.upm.es/~vpablos/others/packages/debian/ ./
deb-src http://babel.ls.fi.upm.es/~vpablos/others/packages/debian/ ./

How do we obtain the packages?

cowbuilder --create
cowbuilder --update
cowbuilder --build file.dsc.

Configuration file "/etc/pbuilderrc" for debian can be found here
To allow others use our packages from apt, we have setup one directory with some packages and run

$ apt-ftparchive packages . | gzip > Packages.gz
$ apt-ftparchive sources . | gzip > Sources.gz

(as explained in http://soleup.eup.uva.es/mario/post/1/446 and in
