    v1 v10  
    11Code for studying lyapunov exponents of translation surfaces and their covers.
    22
    3 TODO:
    4   * See compatibility with other existing code for interval echanges and strata
    5   * It seems to work in most of the examples,
    6    there is a bug for zero lyapunov exponents when decomposing in isotropic components :
     3UPDATE:
     4  * ''See compatibility with other existing code for interval echanges and strata''
     5  compatible with code for quadratic and abelian stratum components
