help needed w. vtroff font change

[Ron Natalie]

The legal fonts in standard troff are R, I, B, S (Roman, Italic, Bold, and
special).  Any others have to be hacked in.  The way vtroff does this is
by having a file called .railmag which maps the vfont names onto a cat
position number.  Once you do this, you may then use .fp.  The program looks
first in the current directory for the railmag file.

As for point size changes you can either use the .ps directive or the \s
inline characters.  See the TROFF manual.  Don't forget that if you change
the pointsize, you probably also want ot change the vertical spacing ammount.
You must do a point size change that corresponds to the font.  Not all fonts
exist in all point sizes.
