Extend math family up to 256 for pLaTeX/upLaTeX/Lamed
Description
This package increases the upper limit of math symbols up to
256, using \omath... primitives. These primitives were
originally introduced in Omega and are currently available in
the following formats: pLaTeX (runs on e-pTeX), upLaTeX (runs
on e-upTeX), Lamed (runs on Aleph, successor of Omega).
