[mom] using chem in mom

[Hans Bezemer]

Dear all,

I would like to use chem along with mom.

This:
.cstart
CH3
bond
CH3
.cend

Results in:
.PS
<pic code>
.PE
After preprocessing it with chem.

But I would like to append arguments after .PS like `CAPTION'
and `TARGET'.

An option could be to add a marker above the chem code:
\# ChemPic: CAPTION "My chemical structure" TARGET
"NoMethane" and use sed or awk to append everything after the ":" to .PS
But is there a more straightforward option to use chem with
mom?

Kind regards,

Hans
