cygwin / bash environment setup
It would be nice if OpenFlow shipped with environment variable scripts for cygwin bash as well as the existing .bat files for cmd... the windows command shell is a real hog if you're used to something more capable. Here's what I'm using:
export WM_PROJECT_DIR=`cygpath -d "C:\Program Files\OpenFlow-4"`
export WM_PROJECT_DIR_=`cygpath -u "$WM_PROJECT_DIR"`
export PATH="$OF_BIN:$OF_BIN/mpi:/c/Program Files/Microsoft HPC Pack 2008 R2\Bin:$PATH"
