SW4 (Seismic Waves, 4th order) implements substantial capabilities for 3-D seismic modeling, with a free surface condition on the top boundary, absorbing super-grid conditions on the far-field boundaries, and an arbitrary number of point force and/or point moment tensor source terms.
This changes the README file to markdown (.md) and adds a few other features. None of the original content was changed but some were added.
Edits were initially committed to add the release notes but now I see it in the release packages! Thanks.
The next commit to this branch will delete the release notes from the README file.
