Re: macro trouble

[Karl Berry]

    I have written a macro (actually it behaves more like an alias) for
    prototypes

It seems that TeX's @macro implementation cannot handle arguments with
multiple lines, I'll add this to the list of failings in the manual.
You'll have to use makeinfo (or texi2dvi) -E.

Although in this case, I'm not sure what the @macro is actually buying
you.  Why not just use @example directly?  Anyway ...

Thanks for the report.
