       I did "which" for all 451 executables found by "ls -l 
/usr/local/bin | grep 'texlive/20' > texlive_20.txt".  All but 3 of them 
were found in "/Library/TeX/texbin/".  The 3 not found were 
lua2dox_filter, pdfatfi, and xindy.mem.  In particular, a2ping was found 
there.


       Anything else?
       Thanks again.
