INSTALLATION NOTES

1. The Dragon tool is based on the OpenUH compiler. Please install 
the OpenUH compiler first without root privileges:

       tar -zxvf openuh-alpha.itanium.tar.gz   for IA-64
   or  tar -zxvf openuh-alpha.i386.tar.gz      for IA-32
       cd openuh
       ./install.sh
      
   If you have questions about what is inside the install.sh script, 
   please review it, but do not attempt to change the paths for the 
   target filenames, otherwise the compiler might not be able to 
   install correctly.
	
2. Install the vcg tool for the purpose of printing the callgraph and 
   control flowgraph. See vcg tool documentation for installation.
     
3. Use the following command to untar Dragon for IA-64:
       tar -xzvf dragon.itanium.tar.gz

   Or use the following command to untar Dragon for IA-32:
       tar -xzvf dragon.i386.tar.gz
