-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/.
