+ksh, sh, zsh).  Most shell scripts use getopt for flags processing, but the
+different versions of getopt on various OSes make writing portable shell
+scripts difficult.  shFlags instead provides an API that doesn't change across
+shell and OS versions so the script writer can be confident that the script
+will work.")
