+     "This package aims to improve of font readability in presentations, especially
+with maths.  The standard CM maths fonts at large design sizes are difficult
+to read from far away, especially at low resolutions and low contrast color
+choice.  Using this package leads to much better overall readability of some
+font combinations.  The package offers a couple of harmonising combinations of
+text and maths fonts from the (distant) relatives of computer modern fonts,
+with a couple of extras for optimising readability.  Text fonts from Computer
+Modern roman, Computer Modern sans serif, SliTeX Computer Modern sans serif,
+Computer Modern bright, or Concrete roman are available, in addition to maths
+fonts from Computer Modern maths, Computer Modern bright maths, or Euler
+fonts.")
