Compilation

$ make

After compilation, two files are produced:

• a shared object library disk-nt.so
• a test executable disk-nt-test

The shared object library can be used in custom programs. The test executable demonstrates a simple dump of quantities for a given choice of spin and mass accretion rate. See the main() function in disk-nt.c.
