+"""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 |
+files, to reduce maximum compilation unit size and allow parallel compilation. |
+ |
+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. |
