The directory tree for the build is as follows:
Top_level
|
+-dist (a directory to hold the compiled gromacs binary tree:
|       ftp://ftp.gromacs.org/pub/gromacs/gromacs-3.3.2.tar.gz)
|
+-mcpp (mcpp binary distribution which can be gotten from: 
        http://mcpp.sourceforge.net/download.html

ReadMe.html,License.txt and GMX_installer.nsi should all reside in the top level directory
