Quartus and source control

Hello all,
I'm interested in implementing a source control system (Subversion) in
the company I work. We do mostly Altera FPGA designs, so our main tool
is Quartus. I would like to know if anyone has done that before, and
how. The main problem with Quartus is that it has no "source file
list", but rather it searches dynamically for files (mostly true for
old design entry methods like AHDL and schematic). Does anyone know of
a tool (maybe a TCL script) that takes a projects and generate a list
of all source files included?
I would be happy to hear about any experience of this kind.

Thanks,
Avishay
