The projects (very small projects) include forms and the conversion with
lazres was working fine at this stage. Then there were a few ifdefs in the
code to keep the code compilable under Delphi and FPC.

For the moment I've got this working:
- I converted a dfm with lazres into lrs (and lfm)
- I edited the form under Lazarus
- to get the code back to Delphi, i renamed lpr to dpr and lfm to dfm
- I opened the project in Delphi and there were all changes I made under
Lazarus and it seems it compiled correctly with Delphi and FPC

I forgot this, then it's a part of the TODO list:-)

My professors are in large majority fans of free software, so the talks should
be successful, I'll be talking with my professor tomorrow morning (CET), so
in the evening I could have some further details on this issue.
Lazarus is GPL/LGPL licensed? This tool should be also licensed this way to
keep it coherent, I think.

Thanks for all opinions,
