AsturFit is an octave package for fitting equation of state functions to energy-volume and pressure-volume data in solids. The ~/doc directory contains the documentation: asturfit.pdf and asturfit.txt (plain ascii text written in reStructuredText format). This includes instructions for installing the package, examples of use, and a description of all routines. The sources reside in the ~/src directory. A number of data sets, example test scripts, and the output of the tests, can be found in the ~/test directory.
