Hello, I want to use optparse on a gem packaged bin/ file  
(eg/usr/lib/ruby/gems/1.8/gems/mypackage/bin/foo)

The goal is to make foo usable from the command line without anything  
else except the name of the file (no .rb, no ruby ./something)  
So, the Ruby file in bin/ directory don’t have .rb extension and  
includes this as the first line of code  
#!/usr/bin/ruby

So does several packages I’ve seen (rcov for example)

But for a reason I don’t understand the code above doesn’t works…  
From the stdlib doc, tested on a mygem/bin/foo :

#!/usr/bin/ruby  
require ‘optparse’

options = {}  
OptionParser.new do |opts|  
opts.banner = “Usage: example.rb [options]”

```
 opts.on("-v", "--[no-]verbose", "Run verbosely") do |v|
   options[:verbose] = v
 end

```

end.parse!

p options  
p ARGV

foo --verbose  
displays  
{}  
[]

Why ? What’s wrong ??

Thanks

It did display {:verbose=\>true} as expected.

Does gem’s wrapper do something wicked?
