gEDA: attribs file

[Karel Kulhavý <clock@twibright.com>]

If I understand the whole stuff correctly, there is a hardwired attribs
file that defines attribs for gnetlist output.

However on Ronja I am using gnetlist together with GNU Make and this
design is not reentrant. It means that if I want to generate 2
different files with two different sets of attributes and set up make -j 2
(concurrent job execution for speed up for example on SMP systems), then
there is no way how to implement it correctly.

I think using make and concurrent jobs and autogeneration of output files
is a sensible way and that it is the way how people can be expected to use
gnetlist in the future.

I suggest to make possible to at least specify the filename of the former
attribs file on commandline.
