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" (formerli regulations ISO 31/XI, now ISO\,80000).
+ 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 se 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 pmisomath 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.
