obspy.io.gse2.libgse2

Lowlevel module internally used for handling GSE2 files.

Python wrappers for gse_functions - The GSE2 library of Stefan Stange. Currently CM6 compressed GSE2 files are supported, this should be sufficient for most cases. Gse_functions is written in C and interfaced via python-ctypes.
