+The \fBTcl_FindExecutable\fR procedure computes the full path name of
+the executable file from which the application was invoked and saves
+it for Tcl's internal use.
 The executable's path name is needed for several purposes in
 Tcl.  For example, it is needed on some platforms in the
 implementation of the \fBload\fR command.

+\fBTcl_GetNameOfExecutable\fR simply returns a pointer to the
+internal full path name of the executable file as computed by
+\fBTcl_FindExecutable\fR.  This procedure call is the C API
