I'll see what I can do about documentation; any input on the above related to that will be helpful.
This might be a good time to mention that I've thinking about writing up more detailed documentation than what may be suitable for the GCC manual and posting it either on the Wiki or someplace where users can easily find it. I should be able to get to it once all my patches have been approved and committed and I'm done fixing bugs in them. If you (or anyone else) have suggestions I'd be grateful for them. Martin
