#Makefile containing the rules for generating DDR blobs automatically. Don't run this directly - it needs to be included in another 
#file that defines (at least) CFLAGS and JAVA

#4 stage process - similar but slightly different for C and C++
#1. Generate a C/C++ file consisting entirely of #includes
#2. Pre-process that C/C++ file to create a .i file. For C source, run a cleaning process
#3. Run the C++ parser (extract_structures) to produce an .xml file containing structure data
#4. Transform the data in the XML file, and the #defines in the original header, into C or C++ to be compiled
