+The PM-ISOmath package, version 1.0.04 of 2018
+Original author: Claudio Beccari, 2017
+LaTeX Project Public Licence LPPL v.1.3c (or later)
+
+The PM-ISOmath name stands for "Poor Man ISO Math". In substance
+ this package is a poor man solution to the task of typesetting
+ math fulfilling the ISO regulations "for physical sciences and
+ technology" (formerly regulations ISO 31/XI, now ISO\,80000).
+ These regulations refer mostly to the family, series and shape
+ of fonts to be used with symbols of various nature.
+
+This package gets inspiration from the ISOmath package by Günter
+ Milde, but tries to get the same results without using any math
+ [font] groups (or families). As pdfLaTeX users may recall, this
+ typesetting program may see at maximum 16 math [font] groups (or
+ math font families); sometimes this number results in an error
+ that forbids the user to use the symbols s/he needs.
+
+The trick used in this package consists in employing text fonts
+ within the \text command (defined by the amsmath package that,
+ therefore, is a dependence to which pm-isomath is subjected) and
+ chose text font families, series, and shapes to be used within
+ that command argument.
+
+The commands are such as to fulfil some math requirements; for
+ example while in the scope of the \boldmath declaration, the
+ series is automatically set to bold without any user intervention.
+ The font size is automatically taken care by \text, so that fonts
+ have the correct size also while typesetting exponents or subscripts.
+
+Nevertheless, through proper advanced command options, the user
+ remains the person principally responsible of using the right
+ font for the right symbol in a document that must fulfil the
+ ISO regulations.
+
+This package is usable only with pdfLaTeX; LuaLaTeX and XeLaTeX
+ can access OpenType math fonts through the package unicode-math,
+ and with the "math-style=ISO" option they have the math switching
+ commands agree with the ISO regulations.
+
+pdfLATeX users have available some packages to fulfil the ISO
+ requirements; principally the ISOmath package that is subject
+ to a number of limitations due the the particular math environment
+ of the user, and libertinust1math that produces a complete set-up
+ with math fonts that match very well text fonts that are darker
+ than the standard default Computer Modern ones (including the
+ CM-super and the Latin Modern ones).
+
+This package works very well with the Latin Modern fonts; in
+ practice in math mode it uses the same Latin text fonts, and
+ the corresponding families, series, and shapes of the LGR
+ encoded CBfonts; it may work also with the CM and the CM-super
+ fonts, but the original author never uses them, therefore he
+ cannot guarantee any suitable result.
+
+For installation of this package, simply run the pm-isomath.dtx
+ through pdfLaTeX (and only pdfLaTeX); move the produced sty file
+ to the .../tex/latex/pm-isomath/ folder; if it does not exist,
+ create it; similarly move pm-isomath.dtx to .../source/latex/pm-isomath/
+ and pm-isomath.pdf to .../doc/latex/pm-isomath/.
