[erlang-questions] Erlang documentation -- a modest proposal

[Éric Pailleau]

Hi,
I see an interest in keeping all source code in abstract code at least as a compilation option. 
This could allow to beautify code automatically with the rules of owner by rewriting back to disk the source code. 
Numbers of blanks per tabulation,  max width of code,  some want 80 colons, some other 100 for example. 
This could help to create a tool to let respect the coding standard of owner project. 
Regards
