@c The following macro marks words that aspell should ignore during
@c spellchecking. Within Texinfo it has no effect as it merely replaces
@c the macro call with the argument itself.
@macro nospell {arg}
\arg\
@end macro
@c The following macro works around the Info/plain text expansion of @code{XXX}
@c which is `XXX'. This looks particularly bad when the macro body is
@c single or double-quoted text, such as a property value `"position"'.
@c The mnemonic to remember this macro is Quoted CODE.
@ifinfo
@macro qcode{arg}
\arg\
@end macro
@end ifinfo
@ifnotinfo
@macro qcode{arg}
@code{\arg\}
@end macro
@end ifnotinfo
@c The following macro works around the Info/plain text expansion of @code{XXX}
@c which is `XXX'. This can be confusing when the macro body itself
@c ends with a transpose character, such as `x''.
@c The mnemonic to remember this macro is Transpose CODE.
@ifinfo
@macro tcode{arg}
\arg\
@end macro
@end ifinfo
@ifnotinfo
@macro tcode{arg}
@code{\arg\}
@end macro
@end ifnotinfo
@c The following macro is used for the on-line help system, but we don't want
@c lots of `See also: foo, bar, and baz' strings cluttering the printed manual
@c (that information should be in the supporting text for each group of
@c functions and variables).
@c
@c Implementation Note:
@c For TeX, @vskip produces a nice separation.
@c For Texinfo, '@sp 1' should work, but in practice produces ugly results
@c for HTML. We use a simple blank line to produce the correct behavior.
@c
@c The macro is named @xseealso now because Texinfo introduced its own @seealso
@c command. But, instead of modifying all source files, the build system uses
@c the munge-texi script to convert @seealso to @xseealso.
@macro xseealso {args}
@iftex
@vskip 2pt
@end iftex
@ifnottex
@end ifnottex
@ifnotinfo
@noindent
@strong{See also:} \args\.
@end ifnotinfo
@ifinfo
@noindent
See also: \args\.
@end ifinfo
@end macro

@c non-macro items

@c These may be useful for all, not just for octave.texi.
@tex

@end tex
@c Make the apostrophe in code examples cut-and-paste friendly so programmers
@c can take examples from the Octave manual and directly run them in Octave.
