In this final section of Library, we give some example Gnuastro
programs to demonstrate various features in the library. All these programs
have been tested and once Gnuastro is installed you can compile and run
them with Gnuastro’s BuildProgram program that will take care of
linking issues. If you do not have any FITS file to experiment on, you can
use those that are generated by Gnuastro after
make check in the
tests/ directory, see Quick start.
