### This tool creates a file which maps overlay section names and source file names to overlay IDs.
|
|
### custom GDB build then processes this source map and uses it to identify what overlay a source file belongs to.
|
|
### (This makes it a lot easier to identify which overlapping overlay is used for a given input location).
