'''info script''' ''?filename?''

If a Tcl script file is currently being evaluated (i.e. there is a call to Tcl_EvalFile active or there is an active invocation of the [source] command), then this command returns the name of the innermost file being processed. If ''filename'' is specified, then the return value of this command will be modified for the duration of the active invocation to return that name. This is useful in virtual file system applications.

Otherwise, if the file is not being [source]d in or processed by Tcl_EvalFile, the command returns an empty string.
