Stemming from this question and with due credits to @morbusg's answer, I was able to create a very fundamental symbol for the
circuits.ee.IEC TikZ library, the AC voltage source. I call it the
ac source. The code for it is here.
I'd like it to be added to the abovementioned TikZ library, but I don't know how. I don't have a SourceForge account. I'm not familiar with SVN, or any source control system for that matter. My idea is to contact Till Tantau or Mark Wibrow so that they can refactor it to their coding style, but I don't see their e-mail addresses in the
pgfmanual. Any ideas?
