| |
| 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_script 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. |
