SYNOPSIS:   
  To use a Coxeter function, either define that function alone using the
  command with(Coxeter,<function>), or define all functions in the Coxeter
  package using the command with(Coxeter). Whenever there is a conflict
  between a procedure name in Coxeter and another name used in the same
  session, use the long form Coxeter[<function>].
  The functions available are:
    Base         CartanMatrix   CharPoly   ClassRep      ClassSize
    CoxMatrix   CoxNumber      Cprod       Degrees        Diagram
    Exponents    HighestRoot    Index       Induce         InteriorPt
    Iprod        IrrChars       LengthGF   LongestElt    MultPerm
    NameOf      NumRefl        Orbit       Orbit_Size     Perm2Word
    PermChar    PermRep        PosRoots   Presentation   Rank
    Reduce       Reflect         Restrict    RootCoords    Size
    StabChain   Vec2FC
  Additional functions are provided in the Weyl subpackage.
  For a detailed introduction to the package, consult the TeX document
  "A Maple Package for Root Systems and Finite Coxeter Groups," which
  should be available with every installation of the Coxeter package. For
  more information on a particular function, request help via the commands
  ?Coxeter[<function>]  or  ?Coxeter,<function>.
  The names A1,A2,..., B1,B2,..., C1,C2,..., D2,D3,..., E3,E4,...,E8, F4,
  G2, H3, H4, I2, e1,e2,..., and s1,s2,... play special roles as global
  variables in the package and should not be assigned values by the user.
