   Welcome to the BIGSTICK page!

        BIGSTICK is a flexible code for computing many-fermion
wave functions in an occupation representation basis. This is also
sometimes called the interacting shell model.

      You can find the free, open source code here.
       You can also download it by
   "git clone"
        This distribution includes the source code (in Fortran 90), a Makefile, the manual, and some example inputs.  You need a Fortran compiler; it compiles with gfortran and Intel fortran.

       The manual is also available on the arXiv.
