"""Ectrans is the global spherical Harmonics transforms library,
extracted from the IFS. It is using a hybrid of MPI and OpenMP
parallelisation strategies. The package contains both single- and double precision
Fortran libraries (trans_sp, trans_dp), as well as a
C interface to the double-precision version (transi_dp)."""
