| Subject: | Document optional parameters to $usage->die() |
Hi!
Just started using your module - thanks for working on this.
One thing I nearly always need to do is die with usage prepended with a
reason for the failure when a user has provided a value that is out of
range or otherwise invalid.
I was just starting to add this functionality to your when I saw that
$usage->die() can already take an optional hashref with pre_text and
post_text arguments.
So, attached is a small patch that simply documents these optional
arguments :)
Cheers,
Andrew
