+     "Pxfonts supplies virtual text roman fonts using Adobe Palatino (or
+URWPalladioL) with some modified and additional text symbols in the OT1, T1,
+and TS1 encodings; maths alphabets using Palatino/Palladio; maths fonts
+providing all the symbols of the Computer Modern and AMS fonts, including all
+the Greek capital letters from CMR; and additional maths fonts of various
+other symbols.  The set is complemented by a sans-serif set of text fonts,
+based on Helvetica/NimbusSanL, and a monospace set derived from the parallel
+TX font set.  All the fonts are in Type 1 format (AFM and PFB files), and are
+supported by TeX metrics (VF and TFM files) and macros for use with LaTeX.")
