Comment (by neteler):
Here how to test which files are used (expected: via GDAL/PROJ):
{{{
PROJ_DEBUG=ON CPL_DEBUG=ON m.proj proj_in="+init=epsg:4326"
proj_out="+proj=longlat +datum=NAD27" coordinates=-100,40 -d
}}}
The debug messages contain the datum shift file usage information.
TODO: find test case for ntf_r93. Could be done by using the values from
https://github.com/OSGeo/proj.4/blob/master/nad/testIGNF
within m.proj.
