The directory 

http://www.ccs.neu.edu/research/demeter/tools/master

contains the source code for the Demeter Tools/C++.

ftp://ftp.ccs.neu.edu/pub/people/lieber/sources/demeter-master.tar.gz

contains a compressed tar file of the same information.

The directory is huge and contains some outdated information but
is published here for the benefit of those who have to maintain
Demeter/C++ applications and port them to new platforms.

The source code might also be useful to researchers.
Where is the Demeter Tools documentation source?

For Demeter/C++ it is in:
http://www.ccs.neu.edu/research/demeter/sources/DemeterC++/docs

We focus our efforts now on Demeter/Java: see

http://www.ccs.neu.edu/home/lieber/Demeter-and-Java.html

for information and free source code.

Enjoy.
