+"""This is a helper script for IDE developers. It allows you to
+extract information such as list of targets, files, compiler flags,
+tests and so on. All output is in JSON for simple parsing.
+
+Currently only works for the Ninja backend. Others use generated
+project files and don't need this info."""
