Module Gr.Lowlevel

This module contains the bindings to the lowlevel C interface.

Lowlevel bindings to the GR-framewokr C interface.

For the documentation refer to the GR Reference.

The lookup of the "libGR.so" library can be overriden providing the full path to the library so file by setting the LIBGRPATH env variable.
