The main purpose was to better understand Euler flow.
The code solves the basic Euler equations of gas dynamics, by using a
fully implicit Newton iteration (inspired by Sandia's Aria code). The
-code may be configured by an input deck to run different simulations
+code may be configured by an input file to run different simulations
on different meshes, with differing boundary conditions.

The original code and documentation was later slightly modified by Wolfgang
too much trouble.
