You probably know this already but just in case:
- http://www.gnu.org/software/glpk/glpk.html GNU Linear 
  Programming Kit (GLPK) "supports the GNU MathProg 
  language, which is a subset of the AMPL language."
  (Includes a translator for GNU MathProg and 
  documentation.)
- http://www.jeannot.org/~js/code/index.en.html#PuLP 
  PuLP "is an LP modeler written in Python.
  PuLP can generate .LP and .MPS files and call GLPK, COIN 
  CLP/SBB, CPLEX or XPRESS to solve linear problems."

fwiw,
