GNU General Public Licence, version 3 The package astroTools provides assorted command-line tools for astronomy and astrophysics, written in Fortran. The package is currently in the alpha stage; many programs sit around on my computer, waiting to be gathered, tidied up and added — stay tuned (April 2016). The default installer uses CMake. You will need to install the libraries libSUFR and libTheSky to compile astroTools. The code has been used with gfortran (4.8 or newer), g95 and Intel Fortran and can be used under the conditions of version 3 of the GPL. AstroTools is developed by AstroFloyd.
