+Components
+----------
+The fontch V2.2 package is composed of the following files:
+ README -- this file
+ fontch.tex -- main macros
+ bsymbols.tex -- macros for boldface symbols
+ TS1mac.tex -- macros for the TS1 companion symbols
+ DSmac.tex -- auxiliary file for the DStroke option
+ fontch.pdf -- manual of fontch
+ fontch_doc.tex -- source of manual
+
+Description
+-----------
+ This package allows, in plain TeX, to change with a single
+command the size of all fonts that are used for text input and math input.
+Main text fonts of sizes 8, 10, 12, 14, 20 and 24 points are available.
+Fonts of sizes 5, 6, 7 and 9 points are used in subscripts and subscripts of
+subscripts of other main sizes.
+In addition fontch gives support to:
+ - boldface math-italic and boldface math symbols,
+ - T1 Latin Modern fonts,
+ - TS1 companion symbol fonts.
+ - AMS fonts for boldface math,
+ - Double Stroke fonts for blackboard bold symbols
+
+Requirements
+-------------
+- In order to use the T1 options LMTone and LMTSone, you need to have installed
+ the Latin Modern fonts of version 1.000 or larger. Older versions of LM fonts,
+ where the cork encoded fonts had names as cork-lmr10 (instead of ec-lmr10)
+ are incompatible with fontch-2.1. For those fonts you can use fontch-2.0
+ which is incompatible with the new naming convention. The old package is in
+ CTAN:/tex-archive/obsolete/macros/plain/contrib/fontch20.tar.gz
+- In order to use the AMSfont option you need to have installed the AMS fonts.
+- In order to use the DStroke option ou need to have installed the Double
+ Stroke fonts.
+
+Installation
+------------
+ You have only to put the macro files fontch.tex, bsymbols.tex,
+ TS1mac.tex and DSmac.tex in any sensible place in the texmf tree, like
+ .../texmf/tex/plain/fontch/
+
+It is also commendable to put this README file in a proper place such as
+
+ .../texmf/doc/plain/fontch/README
+
+Usage
+-----
+ For using fontch.tex with the original TeX OT1 fonts (Computer Modern)
+just put at the beginning of the document:
+ \input fontch.tex
+
+The file bsymbols.tex provides macro definitions for boldface versions
+of math symbols. For using it just input the file where you need it.
+
+The fontch package has four options for handling different kinds of fonts:
+
+ - LMTone for Latin Modern T1 fonts.
+ - LMTSone for the TS1 companion symbol font.
+ - AMSfont for AMS fonts used for boldface math.
+ - DStroke for Doublestroke fonts providing blackboard-boldface symbols.
+
+The four options are independent. They are activated by setting the
+corresponding variable before calling fontch.tex. For example for
+activating all the four options and using the macros for bold math
+put at the beginning of the document:
+
+ \let\AMSfont\relax
+ \let\DStroke\relax
+ \let\LMTone\relax
+ \let\LMTSone\relax
+ \input fontch.tex
+ \input bsymbols.tex
+
+NOTES:
+-----
+ (1) There is one modification of the standard behavior of plain TeX. Plain
+ TeX defines for the font #3 the same font (tenex) for text, script and
+ scriptscript. That is aw full. The fontch package uses sevenex for
+ script and fiveex for scriptscript, as for the other fonts.
+
+ (2) The use of files il1-t1.tcx or il2-t1.tcx is recommended together
+ with the LMT1 fonts.
+
+ (3) Only the cmcs, cmmib, cmbsy and cmex AMS fonts are supported. These
+ are used for small caps and for boldface math-italic and boldface
+ Greek symbols. The other AMS fonts like the Euler, Cyrillic and extra
+ symbols are not supported.
+
+ (4) Only the roman Doublestroke font is supported. The sans serif version
+ is not supported.
+
+ (5) There are two main uses of boldface math. One case is the use of
+ isolated bold characters or symbols inside a formula. For this case
+ fontch provides bold versions of math symbols and the macro \mb for bold
+ math-italic characters. The plain TeX macro "\bf" yields roman-bold
+ characters in math mode. The name of the bold version of a math symbol
+ is obtained adding the prefix "bf" to the name of the normal symbol. For
+ example a boldface italic "a" is {\mb a}, a boldface roman "P" is
+ {\bf P}, a boldface \Sigma is \bfSigma, a boldface \iff is \bfiff.
+
+ The other case is when one wants to write a complete formula in
+ boldface, for example inside a title. For this case fontch has the
+ macro \setmathbold that changes the font families 1 (cmmi) and 2 (cmsy)
+ to the bold versions cmmib and cmmbsy. The macro \unsetmathbold resets
+ the families 1 and 2 to their original values. These macros should be
+ put before and after the formula.
+
+ (6) Usually the macro \setmathbold does not change the whole formula to
+ boldface. This is due to the fact that in math mode some symbols
+ come from family #0 (cmr) or #3 (cmex) such as "+" or \int. Fontch
+ provides macros for the symbols that come from family #0, For
+ example the bold version of "(" is \bflparen.
+
+ (7) Math symbols of family #3 (cmex) do not have bold versions. In particular
+ \int, \sum and \prod. Nevertheless \smallint is of cmsy and does have
+ a bold version.
+
+Modifications from version 2.1
+------------------------------
+Version 2.2 is a minor bug correction version.
+The main change is the inclusion of the fontch.pdf file.
+
+Modifications from version 2.0
+------------------------------
+Version 2.1 is a minor bug correction version.
+The main change is the change in the name of
+the cork-encoded LM font files to the new
+naming conventions. (cork-lmr10 -> ec-lmr10, etc.)
+Fontch-2.1 is compatible with LM-1.000 or newer versions.
+Older versions of LM fonts are not compatible.
+
+Modifications from version 1.3
+------------------------------
+
+Version 2.0 is a mayor revision.
+
+There are many improvements such as
+ -- Proper handling of smallcaps
+ -- Support for bold-math
+ -- Support for AMS fonts
+ -- Support for blackboard boldface
+ -- Correction of bugs and scaling.
+
+The behavior of V2.0 should be compatible with V1.3 except for case explained
+in Note (1).
