I like it, and actually I'll go further than you because none of the scripts 
in base need to have @TOP@ expanded at all.  This simplifies expandVars.pl 
which no longer needs to have the special bootstrap, but I think we still 
need to include it so we can provide a way for scripts outside of base to add 
the path @EPICS_BASE@/lib/perl to their @INC list.

Thanks, I will add this approach before R3.14.10 comes out.
