Seems I was too brief.  I am using the attached script to generate the
*.tfm and *.vf from the *.afm files.  I am using the Alladin PS fonts
and the Bitstream 500 fonts.  I even have a script to generate the
psnfss *.sty files for the Bitstream 500 fonts.

When I was using the metafont *.tfm files, I couldn't get my fonts to
print certain ligatures and other characters because I don't have actual
Adobe fonts.  I created my own *.tfm and *.vf files using this script. 
I think the problem is that I have to generate my own files to match the
actual postscript fonts I am using.

Seems my versions of the fonts don't have the needed entries.  But I
see in my *.afm files:

C 94 ; WX 479 ; N asciicircum ; B 51 323 428 698 ;
C 195 ; WX 273 ; N circumflex ; B -8 604 281 750 ;

C 126 ; WX 479 ; N asciitilde ; B 50 173 429 336 ;
C 196 ; WX 273 ; N tilde ; B -14 610 287 737 ;

However, \~{} and \^{} print nothing, while \asciitextcircum and
\asciitexttilde work fine.

Any ideas?  My guess is that I am missing something in the attached
script, but I have no idea what it could be since all the other
characters like copyright symbol and ligatures print fine.  Is it wrong
not to encode them as 8r?  I don't have any need for *.dvi files because
I output only PDF and use latex2html for html output.

Also, my script has to use the raw *.tfm files for smallcaps in my *.map
files because I don't follow the standard font naming convensions, and
TeX will not find them.  It assumes smallcaps in a virtual font have a
certain name extension.  However, smallcaps are not related to my
problem above.

My book is at http://www.postgresql.org/docs/awbook.html.  

I got most of this information from dvips.dvi.

I am familiar with installing fonts in troff, but this is my first font
install process for TeX.
