| """Generate aggregate .cpp files that include multiple V8 binding .cpp files. |

| This can be a single output file, to preserve symbol space; or multiple output |

| |
| Usage: |
| aggregate_generated_bindings.py COMPONENT_DIR IDL_FILES_LIST -- OUTPUT_FILE1 OUTPUT_FILE2 ... |
| |
| COMPONENT_DIR is the relative directory of a component, e.g., 'core', 'modules'. |
| IDL_FILES_LIST is a text file containing the IDL file paths, so the command |
| line doesn't exceed OS length limits. |
| OUTPUT_FILE1 etc. are filenames of output files. |
