-    (description
-     "The library provides a sort of useful classes, algorithms, and
-high-level protocols to support an application programmer in writing such
-software.  The most remarkable feature is the absence of a trusted third
-party (TTP), i.e. neither a central game server nor trusted hardware
-components are necessary.
-
-The corresponding cryptographic problem, actually called Mental Poker, has
-been studied since 1979 (Shamir, Rivest, and Adleman) by many authors.
-LibTMCG provides the first practical implementation of such protocols.")
