This package provides tools to simplify perturbation expansions of partial differential equations.

Equations (or systems of equations) can be transformed into a dimensionless form, containing small parameters which will be used for the expansions.

Suitable asymptotic expansions of the solutions can be substituted into the equations, resulting in sets of equations for the different orders of the small parameter.

The leading orders of the unknown functions can be determined by a heuristic algorithm.
