The syntax for #-- comments is:
The #-- function is for parsed multi-line comments, it parses the text between #-- and --# but does not add the output to the file being built.
Note: Nift will skip to the first non-whitespace (ie. to the first character that is not a space, tab or newline) after a multi-line comment and inject it to the output file where the comment started. If you want to prevent Nift from doing this put a '!' after the comment close tag, eg.:
multi-line comment without skipping trailing whitespace
