"""Does nothing.
The purpose of this script is to allow for source file dependencies within GN
to be attached to targets that do not typically support them, such as groups.
For example, instead of creating a group target, a pw_python_action target to
run this script can be created. The script can be given a list of input files,
causing GN to rebuild the target and everything that depends on it whenever any
input file is modified.
This is useful in the case where metadata is attached to a group of files but
not collected into a generated_file until a later target.
