Hello,

I would like to be able to load and interpret custom design rules in a 
third-party tool. Meanwhile the grammar of S-expressions is pretty 
clear, I wasn't able to find a grammar for the constraint section of 
custom rules. Is there a document that states the grammar of the 
language? The official documentation is pretty vague 
(https://docs.kicad.org/6.0/en/pcbnew/pcbnew.html#custom_design_rules) 
regarding the precise grammar.  I know that I could extract it from the 
class DRC_RULES_PARSER, however, if there is a grammar available, I 
prefer to use it.

Thank you for your help in advance_
Jan
