Thanks for the note about two digit option. I did not know about that. I came
across another usenet message and it showed a different way of putting the
USAGE together. I like how this make the code look neater and more readable.
Time for more questions :)
* Is there a more detail/in-depth document discussing getopts and USAGE? There
is a bit in the man pages (man ksh) but nothing easily understandable.
* I expanded my DESCRIPTION to have paragraphs, but when I make the man page it
pushes it all together. Is there a way to have a bit more editorial control
over the content of this section? I tried to embed \n characters, but they are
ignored.
* for this test I set my flags to be 'aaa' or 'bbb', yet 'a' or 'aa' will be
acceptable. Is there a way to force to a specific value? or does this take
the first unique value (e.e 'aax' versus 'aaa'?)
* How did the suboptions (20 and 21) become negative?
Thanks
Eric
