        - tweak the file test again to exclude directories; (is this going to
          turn into something more convoluted in several releases? probably)

0.109     2021-06-20 21:10:22-04:00 America/New_York
        - use "-r" test instead of "-f" test, to allow use \ 
on (say) named
          pipes (thanks, L. Alberto Giménez!)
        - update author information
        - add perl support section to docs
