Very long comments that span across many lines may be printed using the OBTW keyword. These multi-line comments will span until the first TLDR:

OBTW
What a
long comment
zzz
TLDR

When we have many lines of comments, it can be tiresome to always prefix them with BTW. OBTW comments save us time there.

As with BTW comments, everything inside OBTW comments is ignored.

OBTW is an emphatic shorthand for “oh, btw.”
TLDR is an acronym for “too long; didn’t read.”
