Working with roms projects

Here is a [movie](http://pong.tamu.edu/~rob/movies/roms_project.mov) [~200 Megs] showing how to download ROMS using subversion, and start a project.

SAGE for symbolic mathematics

[SAGE](http://www.sagemath.org/) is a symbolic mathematics solver, based in python. I have compiled it, and done some simple test cases, and it seems to work well. This may be a good, free alternative to Mathematica for doing simple analytic solutions.

Universal gfortran

The folks over at R (the statistical programing language) have developed a [universal gfortran](http://r.research.att.com/tools/), installed with a normal Mac installer (unlike the version over at [Mac HPC](http://hpc.sourceforge.net)). It has been used to compile universal binaries for [scipy](http://www.scipy.org) successfully, so this seems like a good option to use.
