+
+After:
+
+\input txfn
+
+the new text families TXRoman, TXSans and TXTypewriter
+are declared and new math encodings TX and PX are declared.
+
+TXRoman: the same as Times, but more variants \sl, \bsl, \csc and
+ \bcsc are defined and extension font is used from TXfonts
+ (all text-companion symbols are available).
+TXSans: the same as Helvetica, but more variants \csc and \bcsc
+ are defined and extension font is used from TXfonts.
+TXTypewriter: Special typewriter-like family from TXfonts.
+
+TX: TXfonts will be used in all families of math fonts.
+PX: fam0 (roman) will be the same as current text roman variant,
+ fam1 (math-italic) will be the same as current text italic,
+ other math symbols will be used from TXfonts.
+
+Control sequences of all TX symbols (many hunderds) are available
+in math mode after \setmath[//] if \def\fomenc{TX} or
+\def\fomenc{PX} is used. See TX documentation for more information
+about names of these sequences and symbols shapes.
+
+Not all possible math alphabets are allocated. For example, typewriter
+and slanted variants are not allocated by default in order to keep the
+space of math families. You can add math alphabets by hand:
+
+* Sans serif bold slanted variant for math (usable for vectors):
+
+\addcmd\mathfonts {\newmathfam\vecfam \loadmathfam\vecfam [/txbsssl]}
+\addcmd\mathchars {\def\vec##1{{\fam\vecfam##1}}}
+
+* \sl variant for math (I don't know how it is usable):
+
+\addcmd\mathfonts {\def\tmpa{bold}%
+ \ifx\mathversion\tmpa \def\tmpa{b}\else\def\tmpa{}\fi
+ \newmathfam\slfam \loadmathfam\slfam [/tx\tmpa sl]}
+
+* \tt variant for math (I don't know how it is usable):
+
+\addcmd\mathfonts {\def\tmpa{bold}%
+ \ifx\mathversion\tmpa \def\tmpa{b}\else\def\tmpa{}\fi
+ \newmathfam\ttfam \loadmathfam\ttfam [/tx\tmpa tt]}
+
+See end of amsfn.tex file for more examples of math alphabets
+(Euler Fraktur, Euler Script etc.).
