DESCRIPTION

       The software package 4ti2 is a suite  of  command-line  tools  for  addressing  algebraic,
       geometric and combinatorial problems on linear spaces.

DATA STRUCTURE

       The  main  concept  of  4ti2  remains  the same: a project is defined via a file foo[.mat]
       containing the problem matrix.  Related sets such as Graver basis or Markov basis are  put
       into foo.gra and foo.mar, respectively.

       Input  files  and output files usually contain a matrix or a list of vectors (written as a
       matrix) in a standard encoding such as
         2 4
         1 1 1 1
         1 2 3 4

       There are only few exceptions, for example in a file foo.vars  containing  user  specified
       variable names:
         3
         a b x
