=head1 NAME
font2afm - create font metrics (in F<afm> format) for (almost) any font file
=head1 SYNOPSIS
font2afm [options] I<font> ...
font2afm [options] @I<filelist>
=head1 DESCRIPTION
B<font2afm> generates font metrics (in Adobe's F<afm> format) for Type1,
TrueType and OpenType fonts.
B<font2afm> is just a wrapper script around several utilities (B<cfftot1>,
B<pf2afm>, B<ttf2afm>, B<pfm2kpx> and B<ot2kpx>) that do the real work.
All these utilities need to be available on your system.
=head1 OPTIONS
=over 4
=item B<-f>
Force overwriting of existing F<afm> files.
=back
=head1 FILES
=over 4
=item I<font>
This can be any Type1 (in either F<pfa> or F<pfb> format), TrueType or
OpenType (both PostScript- and TrueType-flavored) font.
=item I<filelist>
This should contain a newline-separated list of font filenames.
=back
=head1 SEE ALSO
F<pf2afm> (part of I<GhostScript>), F<ttf2afm> (part of I<pdfTeX>),
F<afm2afm>, F<autoinst>, F<cmap2enc>, F<ot2kpx>, F<pfm2kpx>, F<cfftot1>
(part of Eddie Kohler's I<LCDF TypeTools>).
