The package offers LaTeX support for the fonts PT Sans and PT
Serif developed by ParaType for the project "Public Types of
Russian Federation", and released under an open user license.
The fonts themselves are provided in the original TrueType
format and as conversions to Type 1 format (as kindly allowed
by ParaType). The fonts provide encodings OT1, T1, IL2, TS1,
T2* and X2. The package provides a convenient replacement of
the two packages ptsans and ptserif.
