Re: @macro to accept hyphen

Did not know about the doubling \\.  How is that?  Could you include an example
of a macro with Mathematical expression?  Have written an example for you.


@macro Mtk
@tex
In spherical coordinates, the Laplacian Operator is $\\nabla^2 \\phi(r)$.
$$\\nabla^2 \\phi(r) =
  {1 \\over r^2} {\\partial \\over \\partial r}
  \\bigg\\lbrack r^2 {\\partial \\phi \\over \\partial r}\\bigg\\rbrack$$
@end tex
@end macro

@Mtk
