12.4 Library demo programs

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.
