-  ./bootstrap.sh
-  ./configure
-  make
-  sudo make install
-
-Here is what is installed with 'make install':

-
-== RUNNING CORE ================================================================
-
-First start the CORE services:
-
-  sudo /etc/init.d/core-daemon start
-
-This automatically runs the core-daemon program. 
-Assuming the GUI is in your PATH, run the CORE GUI by typing the following:
-
-  core-gui
-
-This launches the CORE GUI. You do not need to run the GUI as root.
