+ This extension point is used to contribute a script solver that is consulted any place in JSDT where a <code>ScriptReference</code> must be resolved to a workspace-local <code>IFile</code>.
+<br><br>
+An example of typical usage is resolving if a breakpoint's workspace path matches that of a given <code>ScriptReference</code>
