+This script is intended for use as a GYP_GENERATOR. It takes as input (by way of
+the generator flag config_path) the path of a json file that dictates the files
+and targets to search for. The following keys are supported:
+files: list of paths (relative) of the files to search for.
+test_targets: unqualified target names to search for. Any target in this list
+that depends upon a file in |files| is output regardless of the type of target
+or chain of dependencies.
+additional_compile_targets: Unqualified targets to search for in addition to
+test_targets. Targets in the combined list that depend upon a file in |files|
+are not necessarily output. For example, if the target is of type none then the
+target is not output (but one of the descendants of the target will be).
+
+The following is output:
+error: only supplied if there is an error.
+compile_targets: minimal set of targets that directly or indirectly (for
+ targets of type none) depend on the files in |files| and is one of the
+ supplied targets or a target that one of the supplied targets depends on.
+ The expectation is this set of targets is passed into a build step. This list
+ always contains the output of test_targets as well.
+test_targets: set of targets from the supplied |test_targets| that either
+ directly or indirectly depend upon a file in |files|. This list if useful
+ if additional processing needs to be done for certain targets after the
+ build, such as running tests.
+status: outputs one of three values: none of the supplied files were found,
+ one of the include files changed so that it should be assumed everything
+ changed (in this case test_targets and compile_targets are not output) or at
+ least one file was found.
+invalid_targets: list of supplied targets that were not found.
+
+Example:
+Consider a graph like the following:
+ A D
+ / \
+B C
+A depends upon both B and C, A is of type none and B and C are executables.
+D is an executable, has no dependencies and nothing depends on it.
+If |additional_compile_targets| = ["A"], |test_targets| = ["B", "C"] and
+files = ["b.cc", "d.cc"] (B depends upon b.cc and D depends upon d.cc), then
+the following is output:
+|compile_targets| = ["B"] B must built as it depends upon the changed file b.cc
+and the supplied target A depends upon it. A is not output as a build_target
+as it is of type none with no rules and actions.
+|test_targets| = ["B"] B directly depends upon the change file b.cc.
+
+Even though the file d.cc, which D depends upon, has changed D is not output
+as it was not supplied by way of |additional_compile_targets| or |test_targets|.
+
+If the generator flag analyzer_output_path is specified, output is written
+there. Otherwise output is written to stdout.
+
+In Gyp the "all" target is shorthand for the root targets in the files passed
+to gyp. For example, if file "a.gyp" contains targets "a1" and
+"a2", and file "b.gyp" contains targets "b1" and "b2" and "a2" has a dependency
+on "b2" and gyp is supplied "a.gyp" then "all" consists of "a1" and "a2".
+Notice that "b1" and "b2" are not in the "all" target as "b.gyp" was not
+directly supplied to gyp. OTOH if both "a.gyp" and "b.gyp" are supplied to gyp
+then the "all" target includes "b1" and "b2".
