[erlang-questions] Learning Erlang

[Ian]

Hi All,

Is there a book, on-line resource, or even a well written open-source 
project, that would help me understand how to write good clean Erlang code?

I taught myself PHP about 4 years ago, and have recently had to go back 
and modify the first large system I wrote, and I find the coding of that 
system is dreadful! Now that's good in the sense that I have improved, 
but bad in that the code is still bad and its costing me effort while I 
change it now. Its also bad because I should have enough programming 
experience to avoid writing bad code. I've been programming since 74.

I am about to build two web based applications in Erlang, and I don't 
want to wince too much  when I come to enhance them.

Thanks for any tips

Ian
