Simai comments

[MBmasher]

Comments in simai are denoted by || - the comment marker and everything after it, until the next new line, should be ignored

Didn't see the wiki specification for commenting, but it could be a handy feature, do you have exact specification for commenting (and/or other non-gameplay features)?

yeah it doesn't seem to be documented but the feature is recognised by the majdata editor and it's used in some charts
