You can write comments in a Texinfo file by using the
command, which may be abbreviated to
@c. Such comments are
for a person looking at the Texinfo source file. All the text on a
line that follows either
@c is a comment;
the rest of the line does not appear in the visible output.
Often, you can write the
@c in the middle
of a line, and only the text that follows after the
@c command does not appear; but some commands, such as
@setfilename, work on a whole line. You
@c within a line beginning with
such a command.
In cases of nested command invocations, complicated macro definitions,
@comment may provoke an error when
processing with TeX. Therefore, you can also use the DEL
character (ASCII 127 decimal, 0x7f hex, 0177 octal) as a true TeX
comment character (catcode 14, in TeX internals). Everything on
the line after the DEL will be ignored.
You can also have long stretches of text to be ignored by the Texinfo
processors with the
@end ignore commands.
Write each of these commands on a line of its own, starting each
command at the beginning of the line. Text between these two commands
does not appear in the processed output. You can use
@end ignore for writing comments. (For some technical
caveats regarding nesting of such commands, see Conditional Nesting.)
