You use the Texinfo @macro command to define a macro. For example:
@macro macro-name{param1, param2, ...}
text ... \param1\ ...
@end macro
The parameters param1, param2, ... correspond to arguments supplied when the macro is subsequently used in the document (see the next section).
If a macro needs no parameters, you can define it either with an empty list (`@macro foo {}') or with no braces at all (`@macro foo').
The definition or body of the macro can contain any Texinfo commands, including previously-defined macros. (It is not possible to have mutually recursive Texinfo macros.) In the body, instances of a parameter name surrounded by backslashes, as in `\param1\' in the example above, are replaced by the corresponding argument from the macro invocation.
You can undefine a macro foo with @unmacro foo.
It is not an error to undefine a macro that is already undefined.
For example:
@unmacro foo
