gEDA-user: more gedasymbols stuff

[DJ Delorie <dj@xxxxxxxxxxx>]

If you haven't visited www.gedasymbols.org recently, we now have six
active contributors and a couple more in the works.  The symbol and
footprint handlers seem to be working OK now (although I've been
tweaking them madly over the last few days ;) so you can easily browse
through the available stuff.

I just added most of the custom symbols and footprints from my furnace
controller: http://www.gedasymbols.org/user/dj_delorie/

I also added icons for .fp and .sym files, so if you happen to view a
subdirectory without an explicit index page, you get the right icons:

http://www.gedasymbols.org/user/dj_delorie/footprints/

At this point, I think the system is working smoothly enough that I
can be more liberal in giving out CVS accounts.  Please read the cvs
and style guides first though:

I'm also thinking of adding a CSV handler, and coming up with a
standard for using CSV's (comma separated values) to store the
cross-reference information (the info that would go in a "heavy"
symbol).  Something like this:

vendor=digikey
catetory=gates and inverters
symbol,footprint,value,description,partnumber
Quad NAND gates
nand,dip14,7400,7400N,296-14641-5-ND
nand,dip14,7400,74AS00N,296-1521-5-ND
nand,dip14,7400,74LS00N,296-1626-5-ND
Quad OR gates
or,dip14,7432,74HC32N,568-1434-5-ND
or,dip14,7432,SN74ALS32N,296-1495-5-ND
or,dip14,7432,SN74HC32N,296-1589-5-ND

I.e. a number of key=value lines that mean "assume a column that
always has this value", followed by a CSV line for the column names,
followed by the CSV data.  CSV lines without commas are subheadings,
used only for making web pages.
