how to install extra packages through proseeding

[Jin Zhao <jzhao@qcorps.com>]

This seems to be a dumb question but so far I have not figured it out by 
searching documents and email lists.

The preseeding example 
(http://d-i.alioth.debian.org/manual/en.i386/apcs01.html) only says the 
following words: "You can also choose to install no tasks, and force the 
installation of a set of packages in some other way.". I am just 
wondering what is such a "some other way". Should I do some post-install 
scripting for this or there exists something configurable in the preseed 
file?

In Redhat's kickstart, specifying additional packages is very simple. 
Just list the package names in %packages section. Hopefully the debian 
installer can do something similar as well.

Thanks,


Jin
