WCSLIB  5.16
Example code, testing and verification

WCSLIB has an extensive test suite that also provides programming templates as well as demonstrations. Test programs, with names that indicate the main WCSLIB routine under test, reside in ./{C,Fortran}/test and each contains a brief description of its purpose.

The high- and middle-level test programs are more instructive for applications programming, while the low-level tests are vital for verifying the integrity of the mathematical routines.
