% DESCRIPTION:
%
% Defining new PostScript fonts with the New Font Selection Scheme is easy,
% but these macros make it easier. They save on keystrokes, and most
% importantly, they make it easy to change the file names used for fonts
% because you only have to type the file name once instead of 12 times (for
% the 12 standard LaTeX sizes). An optional argument lets you scale the fonts.
%
% These macros are substitutes for the NFSS's \new@fontshape command. For
% information on the purpose of this command, and on how to select fonts that
% are defined with it, see the documentation of the NFSS. If you don't have
% the NFSS, it is available from
% rusmv1.rus.uni-stuttgart.de
% in
% soft/tex/latex-style-supported/New-Font-Selection
% and from
% ymir.claremont.edu
% in
% [.anonymous.tex.inputs.latex-mainz]
% The NFSS is undoubtably the best way to use PostScript fonts (or any non-
% standard fonts) with LaTeX, and is well worth upgrading to.
%
% USAGE:
%
% \newpsfont[<scaling>]{<family>}{<series>}{<shape>}{<filename>}
%
% \newpsfamily[<scaling>]{<family>}{
% {<series 1>}{<shape 1>}{<filename 1>},
% {<series 2>}{<shape 2>}{<filename 2>},
% . . .
% {<series n>}{<shape n>}{<filename n>}}
%
% The scaling argument is optional. Like the \new@fontshape command, these
% commands can only be used in the preamble.
%
% EXAMPLE:
%
% Suppose the Helvetica-Oblique virtual font on your system has the name
% phvro.vf. The following defines the <helvetica> family, <m>edium series, and
% <it>alic shape to be the Helvetica-Oblique font, at the standard LaTeX
% font sizes, scaled by .82:
%
% \newpsfont[.82]{helvetica}{m}{it}{phvro}
%
% This is equivalent to:
%
% \new@fontshape{helvetica}{m}{it}{%
% <5>phvro at 4.1pt%
% <6>phvro at 4.92pt%
% <7>phvro at 5.74pt%
% <8>phvro at 6.56pt%
% <9>phvro at 7.38pt%
% <10>phvro at 8.2pt%
% <11>phvro at 8.979pt%
% <12>phvro at 9.84pt%
% <14>phvro at 11.808pt%
% <17>phvro at 14.1696pt%
% <20>phvro at 17.0068pt%
% <25>phvro at 20.4016pt}{}
%
% The following command sets up the standard Helvetica family:
%
% \newpsfamily[.82]{helvetica}{%
% {m}{n}{phvr}, %Helvetica
% {m}{it}{phvro}, %Helvetica-Oblique
% {m}{sl}{phvro}, %Helvetica-Oblique
% {bx}{n}{phvb}, %Helvetica-Bold
% {bx}{it}{phvbo}, %Helvetica-BoldOblique
% {bx}{sl}{phvbo}} %Helvetica-BoldOblique
%
% (Don't forget the commas.) It is equivalent to:
%
% \newpsfont[.82]{helvetica}{m}{n}{phvr} %Helvetica
% \newpsfont[.82]{helvetica}{m}{it}{phvro} %Helvetica-Oblique
% \newpsfont[.82]{helvetica}{m}{sl}{phvro} %Helvetica-Oblique
% \newpsfont[.82]{helvetica}{bx}{n}{phvb} %Helvetica-Bold
% \newpsfont[.82]{helvetica}{bx}{it}{phvbo} %Helvetica-BoldOblique
% \newpsfont[.82]{helvetica}{bx}{sl}{phvbo} %Helvetica-BoldOblique
% \extra@def{helvetica}{}{}
%
% WHY SCALE FONTS?:
%
% Disclaimer: The suggestions that follow come from someone who doesn't know
% anything about fonts.
%
% Mixing fonts that are not designed to be used together is not for purists,
% but many of us do it anyway. Scaling the fonts can at least correct for
% differences in the x-heights. This is important if you use Computer
% Modern fonts for in-line math and some other fonts for text.
%
% To find out the x-height of the 10pt size of a font, load this style and
% use the command
%
% \showxheight{<filename>}
%
% E.g., \showxheight{phvr} and \showxheight{cmr10} displays
%
% x-height of cmr10 at 10pt is 4.30554pt
% x-height of phvr at 10pt is 5.24998pt
%
% on the terminal. Scaling the Helvetica fonts by 4.30554/5.24990 = .82
% gets the x-heights of these fonts in line. It is best to set the x-heights
% the same for the medium weight, normal shaped fonts, and then scale the
% rest of the fonts in the same family by the same amount.
%
% David Jones has a psfonts.sty that sets up the standard PostScript fonts,
% all scaled so that the x-heights match that of the Computer Modern medium
% roman font. It is available via anonymous ftp from theory.lcs.mit.edu in
% /pub/dmjones.
%
% IMPLEMENTATION:
%
% \scale@stdsizes has at its argument a scaling factor. It uses \font@scale
% to define \scaled@sizes to be the macro whose argument is the name of a
% font, and which expands to the definitions of the standard \LaTeX{} sizes
% for New Font Selection Schemes \new@fontshape command.
