 If this directory doesn't exist during the `cmake` step, then cmake will download and install into `build/test_data/fix_REL-3.1.2.x/fix/`.
 The path to an existing fix file installation can be specified using the `FIX_FILE_PATH` option (see CMake variables summary below).
 
-The fix/ directory (as of v3.1.2) contains most of the netCDF SpcCoeff and TauCoeff files, as part of our ongoing effort to transition toward netCDF-only CRTM.  We expect to deprecate the binary formats in v3.2.x, but code to read / convert binary format will continue.

 As of CRTM v3.0.0, we no longer support legacy build system using autotools. (i.e., configure/make).  Only cmake / ecbuild (a cmake wrapper, but not required) is supported.   Many standalone Makefiles, make.dependencies, etc. have been removed, but not entirely.  Cleanup occurs as we work our way through the repository updating other things.
