We are developing more manuals and examples for MD++.

For now, you can download the tar.gz file and extract it in your
~/Codes directory.  This will create MD++ directory under Codes/

To compile, type e.g.
  cd ~/Codes/MD++
  make fs SYS=gpp build=R

To run, type e.g.
  bin/fs_gpp Examples/example01mo.script

The code can also be compiled on other platforms, such as cygwin,
  make clean
  make fs SYS=cygwin build=R

There are manuals in the Codes/MD++/Doc directory.  They are
  md++_02.pdf
  md++manual.pdf
