+This is the fge font, a font of special symbols for setting Frege's
+Grundgesetze der Arithmetik and the secondary literature.
+
+See the file fge-doc.pdf for information on how to access to these
+symbols from LaTeX.
+
+The original font is written in Metafont and mftrace is used to
+create PostScript Type 1 (pfb) files.
+
+This package contains several characters derived largely from
+the Computer Modern fonts, (c) D.E. Knuth. The spritus lenis
+accent is a simplified version of that in the Ibycus font
+(c) Pierre A. MacKay. The remainder of this work is Copyright
+(c) J.J. Green 2007, 2015 and subject to the LaTeX Project Public
+License.
+
+Further information on the font can be found at

+% This included for backward compatibility with versions
+% prior to 1.17, it was only then that I discovered that
+% what I first thought was an N, then an eta, then an

+% The spiritus lenis and asper accents. Here we don't use
+% \texttt{DeclareMathAccent} but instead \TeX\ primatives; the former
+% is for ordinary symbols which are press-ganged into being accents,
+% the latter is for glyphs designed as accents. The tricky part is
+% selecting the \textt{fge} font by coercing its symbol-code into an
+% appropriate hex-string, we copy the code in the AMS fonts package.
+% \begin{macrocode}
+\def\spirituslenisA{\mathaccent"0\hexnumber@\symfgerm 15}

+% \end{macrocode}
+% There are two versions of the spiritus lenis and asper, variant
+% A from the Ibycus font for classical Greek by
+% Pierre A. MacKay, from work by Silvio Levy's realization of a
+% classic Didot cut of Greek type from around 1800.
+% Variant B is my own, an approximation of the more crescent-like
+% accent used in the original printing. Variant A is the default,
+% since it is prettier; but the translators have asked me to retain
+% the crescent form.

+% The character sizing
+% \begin{macrocode}
+\DeclareMathSizes{10}{10}{7}{5}
+% \end{macrocode}
+%</package>
+% \end{macrocode}
+% \subsection{The font definition files}
+%
+% The declarations,
+% that have to go into the corresponding |.fd| files:
+%<*fdrm>
+% \begin{macrocode}
+\DeclareFontFamily{U}{fgerm}{}
+\DeclareFontShape{U}{fgerm}{m}{n}{%
+ <5><6><7> fgerm10
+ <8><9><10> fgerm10
+ <10.95><12><14.4><17.28> fgerm10}{}

+ <8><9><10> fgeit10
+ <10.95><12><14.4><17.28> fgeit10}{}
+% \end{macrocode}
+%</fdit>
+%
+% The next line goes into all files and in addition prevents \dst{}
+% from adding any further code from the main source file (such as a
+% character table).
