[chirp_users] The meaning of CHIRP...

I am a long time user of CHIRP and I just realized there is a key bit of knowledge I lack... and unless I'm missing it... it is also missing from the web site's FAQ.  Where did the name come from? Does CHIRP stand for something?  Did Dan's first radio keep chirping at him every time he pressed the wrong button?  😉  Inquiring minds want to know... (and I'm preparing to teach a class on CHIRP...)
