Is there any Ruby parser for command inline parameters (ARGV[])?

Hi, I usually do Ruby scripts for some tasks and many of them allow inline=
=20
parameters, for example:

./script1.rb -n -vv -o file.out filein

Is there any Ruby library/gem to parse inline parameters easily? this is,=20
parsing ARGV Array.

Thanks.

There's OptionParser which is included in ruby standard library. Use ri=20
OptionParser to learn more about it (you need to require 'optparse' before =
you=20
can use it)

You can also try "getoptlog" library.
