CRACK is a package for solving overdetermined systems of partial or 
ordinary differential equations (PDEs, ODEs). Examples of programs which 
make use of CRACK for investigating ODEs (finding symmetries, first 
integrals, an equivalent Lagrangian or a ``differential factorization'') are 
included.
