# This assumes you have gcc compilers for whatever language you are
# using: cl for C++ and C, ifort for Fortran 95.
# 
# Note: the C Wrappers and Fortran Module are just prototypes. They are
# incomplete but have enough functionality to get through these examples.
# We would like more complete and better-thought-out interfaces; if you
# have code or ideas please post to the OpenMM forum at the above URL
# (select "Advanced/Public Forums").
#
# This has had only minimal testing, although it has been known to
# work. It is likely to work fine for C and C++. For Fortran, you
# may need to add some of the C/C++ libraries: 
#    -lc -lm -lstdc++ (or -lstdc++.6) -lgcc -lgcc_s
# but this wasn't required for these examples on Centos 5.2 using
# gcc 4.1.2.

# Check whether this is the right capitalization for your install directory.
