Issue #6997 has been updated by eike.rb (Eike Dierks).
Ok, I was a bit blind on that,
I think that I now do understand how it works.
But anyway, the documentation should be improved.
I'd suggest to improve the examples to make it more clear upfront.

Bug #6997: Improve documentation for OptionParser
https://bugs.ruby-lang.org/issues/6997#change-29235
Author: eike.rb (Eike Dierks)
Status: Open
Priority: Normal
Assignee:

Target version:
ruby -v: ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin10]
The documentation for OptionParser should be improved.
The current examples and and documentation do not yet describe
how to access non option args
I suggest to change the simple example in the doc as follows:
opts.banner = "Usage: example.rb [options] file ..."
p "files:" + ARGV
It should be stated explicitely in the description,
that parse! modifies the ARGV and removes all parseable args.
At least that is how I believe that the OptionParser.parse! works?
not yet tried it myself
