# v0.1: ???
# v0.2: Doug Gale
#	- Major rewrite
#	- Automatically pulls in all video driver sources
#	- Creates detailed assembly, annotated with source
#	- Creates link map file
#	- Dumps all debugging information to text file
#	- Support for automatically generated dependencies!
#	- Support to build bochs compatible symbol file
#	- Added variable to allow include paths to be added easily
