I'd suggest to ask that on the dev list ...a few cli issues have been
brought up there lately

I think I must be misunderstanding something about the hasArgs. The
program that follows produces:
[javac] Compiling 1 source file
to /home/users/russel/Progs/OddsByLanguage/Java/CommonsCLI_Test
[java] -D blah=Hello
[java] -D burble=thing
[java] -D flob=adob
[java] -D print
[java]
[java] usage: Usage statement
[java] -D Definition of something.
in both 1.0 and 1.1. I had assumed that print would not be treated
a a
-D option. Alternatively this is a bug in which case I will create a
JIRA issue -- unlikely I suspect though, much more likely to be
something stupid on my part.
Thanks.
