  11 TI cgt6x is a compiler suite for TI DSPs.
  12
  13 The toolchain does pretty weird things, and I'm sure I'm missing some of them.
  14 But still, the tool saves time.
  15
  16 What this tool does is:
  17
  18 - create a TI compiler environment
  19 - create TI compiler features, to handle some specifics about this compiler
  20   It has a few idiosyncracies, such as not giving the liberty of the .o file names
  21 - automatically activate them when using the TI compiler
  22 - handle the tconf tool
  23   The tool
  24
  25 TODO:
  26
  27 - the set_platform_flags() function is not nice
  28 - more tests
  29 - broaden tool scope, if needed
