5 Comments and verbatim quotations

Comments are multiline. They are introduced with the characters ${* and extend up to the nearest pair of characters *}. Comments are removed from the output.

Comments can be disabled using the --Wno-comment option (see feature control).

To reproduce a portion of text verbatim (i.e. without expanding variables and substituting commands in it), enclose it in ‘$[’ and ‘]’ brackets. Newlines and balanced square brackets are allowed within that construct.

The special meaning of the ‘$[ ... ]’ construct can be disabled by the --Wno-quote option (see feature control).
