LOEclipse with Python: Make "runtime" copies of source files uneditable

[t-vi]

Thanks for making LOEclipse!

Here is something that tricked me more than a few times:
When using my Python extension with LOEclipse, debugging (understandably) happens in some file under dist/.ooo-debug (where the extension is installed to).
Now under Python, ".py" files are run, so it is really, really tempting to modify them during / shortly after debugging. But this is a trap: They're not the "source" files (under source/ or classes/) but the distribution files.
This (more or less) leads to losing my edits when I re-run the extension.

It would be great if LOEclipse could prevent me from editing the wrong files.
I'm not sure how to achieve that (making them read-only? making them links to the real file?), but it's really easy to get wrong and I felt very bad when it happened.
