[Groff] testing for a font in a macro

[Jason St Armand]

Hi,

is there a way to check for the existance of a font before setting it
?  I am trying to set the font to CR which works for postscript
output, but when I preview with -T ascii I get a warning message about
CR not being available.

I am happy to ignore the error, but ideally would like to substitute R
if CR is not available.


thanks
