"This package provides an extended set of fonts for use in mathematics,
|
||||
including: extra mathematical symbols; blackboard bold letters (uppercase
|
||||
only); fraktur letters; subscript sizes of bold math italic and bold Greek
|
||||
letters; subscript sizes of large symbols such as sum and product; added sizes
|
||||
of the Computer Modern small caps font; cyrillic fonts (from the University of
|
||||
Washington); Euler mathematical fonts. All fonts are provided as Adobe Type 1
|
||||
files, and all except the Euler fonts are provided as Metafont source. The
|
||||
distribution also includes the canonical Type 1 versions of the Computer
|
||||
Modern family of fonts. The Euler fonts are supported by separate packages;
|
||||
details can be found in the documentation.")
