10 proj_def.dat --- basic default file used by proj.
12 epsg --- Translation of EPSG GCS/PCS codes into PROJ.4 via init= mechanism.
14 epsg-deprecated --- EPSG definitions that have been deprecated. They are
15 not part of 'epsg' anymore, but may have been delivered
16 with earlier versions of 'epsg'.
17 Thus, they might occur e.g. in WMS (Web Mapping Services)

20 definitions that were individually reported.
22 nad27 --- North American Datum 1927 for "init=" definition of
23 State Plane Coordinate Systems (SPCS).

40 init files. Read beginning for usage instructions.
42 test27 --- Unix shell (sh) scripts to test installation of
