RAMSES was developed in Saclay to study large scale structure and galaxy formation. It is now a rather flexible package to be used for general purpose simulations in self-gravitating fluid dynamics. It is written in Fortran 90 with extensive use of the MPI library. It is a free software for non-commercial use only. This code is a grid-based hydro solver with adaptive mesh refinement.  As opposed to "patch-based AMR", cells are refined on a cell by cell basis: it is therefore called a "tree-based AMR". A very simple interface based on "Fortran namelist" can be used to specify runtime parameters. A few routines can be modified to set more complex initial or boundary conditions.
