-"""
-
-Tool to run `Halide <http://halide-lang.org>`_ code generators.
-
-Usage::
-
-   bld(
-    name='pipeline',
-     # ^ Reference this in use="..." for things using the generated code
-    #target=['pipeline.o', 'pipeline.h']
-     # ^ by default, name.{o,h} is added, but you can set the outputs here
-    features='halide',
-    halide_env="HL_TRACE=1 HL_TARGET=host-opencl-gpu_debug",
-     # ^ Environment passed to the generator,
-     # can be a dict, k/v list, or string.
-    args=[],
-     # ^ Command-line arguments to the generator (optional),
-     # eg. to give parameters to the scheduling
-    source='pipeline_gen',
-     # ^ Name of the source executable
-   )
-
-
-Known issues:
-
-
-- Currently only supports Linux (no ".exe")
-
-- Doesn't rerun on input modification when input is part of a build
-  chain, and has been modified externally.
