Equivs - APT - Source - Packages

[Ricardo Lima <rlima@Fe.up.pt>]

Hi,
I am trying to install the xfree86 4.4.0 from sources in a debian
testing machine running kernel 2.6.3.
I was able to compile xfree86 and install it.
Now I would like to use equivs to tell apt that xfree86 4.4.0 is
installed.
I have already tested equivs with xfree86-common and it is working (apt
knows that it is installed).
Now the questions:

1 - How can I know all the packages that the sources of xfree86 4.4.0
provide?
      I know that with apt-cache search show, I can get the information
about the source of a package.
2 - Right now I can tell apt (with equivs) that a package is installed,
BUT can I use only one file to specify that several packages are
installed? How?
