1M? What kind of tube

I tried to desolder a SMD component, a capacitor with solder remover
wick (copper braid), and it's very hard to do it.
The class setup is rework tweezers. It's basically a double tipped
solder iron and you can just pick up the part off the PCB with
hot tipped tweezers.
But us poor-folk just
the case all the thru holes will be too small.

leads are easy, smaller ones take more effort. But
what abot ball grid arrays or other parts with no access to all the
leads. I'm seriously thinking about building a reflow oven.

oscillators except they are six
pin devices, with the extra pins for i2c programmeing. Jitter specs look
good.

Absolutely and very clearly no. This is exactly the same as using the gcc

in that case he is re-selling a GPL'd product and some other product.
The key test again if if the final product is like the DLL, modular and
in theory an end user could replace one part at a time.

If you link in GPL'd code, period. That includes dynamic linking, and
any attempts to wrap the proprietary code in a GPL'd wrapper.
It is easy to come up with counter examples...
So if I write a proprietary program the uses the Motif widget set
and I license it with very restrictive terms and
and autorouting.

don't know if they have done that yet (just
checked, no) but the old (somewhat functional) 10/100/1000BaseT MAC is there
now. The new MAC is in the project's CVS.

Gschem's primary purpose is schematic capture. If what you want is
publication quality schematic drawings use XCircuit.

What would be really nice would be a translator between the two
