===== Installation =====

ASWNS requires the following prerequisites: 
   * a suitable fortran compiler, e.g., gfortran 
   * [[http://www.netlib.org/lapack/double/|lapack library]] or separately the [[http://www.netlib.org/cgi-bin/netlibfiles.pl?filename=/lapack/double/dgtsv.f|XEBLA]] subroutine 

The easiest way to achieve these requirement is simply by typing: 
  sudo apt-get install gfortran liblapack3

Assuming that you have lapack installed (which is the preferred option), you can compile the code with 
  gfortran -O2 ASWNS.f90 nonbarotropic.f90 -llapack -o nonbarotropic.x
  gfortran -O2 ASWNS.f90 kepler.f90 -llapack -o kepler.x

Now you have to executables ./kepler.x and ./nonbarotropic.x that can be used to compute rotating neutron star configurations as discussed [[examples_ASWNS|here]]
