# Package lib

Extension modules for different PETSc configurations.

This package is a holds all the available variants of the PETSc extension module built agaist specific PETSc configurations. It also provides a convenience function using of the builtin `imp` module for easily importing any of the available extension modules depending on the value of a user-provided configuration name, the `PETSC_ARCH` environmental variable, or a configuration file.
