Commonly agreed command line options gem?

Hi,

- Is there a commonly agreed gem for parsing command line options of a
script (ARGV) ?
- If no, does anyone know a good one ?

In all cases (as I'm relatively new to Ruby), what heuristic do you
use to select the gems you need? There actually a lot of gems
available and selecting the good one (still maintained, well tested,
famous ruby developers maybe (?), ...) is pretty hard to me.

Thanks

OptionParser is in ruby core:

I am very happy with Ara Howard's "main" gem, though.
It's very easy to use.

I am used GetoptLong class in stdlib:
http://www.ruby-doc.org/stdlib/libdoc/getoptlong/rdoc/...

Just look at that self-explanatory example and You're ready to go.

My absolute favorite is "trollop". It is mega-mega awesome.
