-"""
-TI cgt6x is a compiler suite for TI DSPs.
-
-The toolchain does pretty weird things, and I'm sure I'm missing some of them.
-But still, the tool saves time.
-
-What this tool does is:
-
-- create a TI compiler environment
-- create TI compiler features, to handle some specifics about this compiler
- It has a few idiosyncracies, such as not giving the liberty of the .o file names
-- automatically activate them when using the TI compiler
-- handle the tconf tool
- The tool
-
-TODO:
-
-- the set_platform_flags() function is not nice
-- more tests
-- broaden tool scope, if needed
