Trollop 1.16.2 has been out for a while now, but I realized I (heavens!)
haven't yet blogged about it.

Exciting features include:

1. Scientific notation is now supported for floating-point arguments, thanks to
Will Fitzgerald [1].
2. Hoe dependency dropped. Finally.
3. Some refactoring of the standard exception-handling logic, making it easier
to customize Trollop's behavior. For example, check this out:


opts = Trollop::with_standard_exception_handling p do
  p.parse ARGV
  raise Trollop::HelpNeeded if ARGV.empty? # show help screen
end


This example shows the help screen if there are no arguments. Previous to
1.16, this was difficult to do, since the standard exception-handling was
baked into @Trollop::options@. The help message would automatically be
displayed if @-h@ was given, but programmatically invoking it on demand was
difficult.

So I've refactored the standard exception handling into
@with_standard_exception_handling@, and if you want fine-grained control,
instead of calling @Trollop::options@, you now have the option to call
@Trollop#parse@ from within @with_standard_exception_handling@.

You don't really need any of this stuff, of course, unless you're _really_
picky about how your exception-handling works. But hey, that's why I wrote
Trollop in the first place....
