In some cases the license-identification header was missing,
so I added that as well. Replaced the remaining headers that
specifically identified "Versions 3.13.7 and higher".
Makefiles and the build system were deliberately excluded.
* main/make-simple:
restore ModuleDirs in caPerlApp
simplify e_flex/antelope path compute
further no need to search for perl modules under bin
skip RELEASE_TOPS
configure: Don't hide any perl scripts being run
missed a TOP
no need to search for perl modules under bin/
drop unnecessary *ModuleDirs
avoided embedded TOP for non sub-modules
