  44     (description
  45      "The library provides a sort of useful classes, algorithms, and
  46 high-level protocols to support an application programmer in writing such
  47 software.  The most remarkable feature is the absence of a trusted third
  48 party (TTP), i.e. neither a central game server nor trusted hardware
  49 components are necessary.

  51 The corresponding cryptographic problem, actually called Mental Poker, has
  52 been studied since 1979 (Shamir, Rivest, and Adleman) by many authors.
  53 LibTMCG provides the first practical implementation of such protocols.")
