some clarification on trallop

[Junkone]

I would like to understand how trallop works.

test.rb
opts = Trollop:ptions do

opt ption1, "do something"
opt ption2, "do different something"

end


so i can run test.rb <arguement1>

If arguement 1 matches ption1, it will perform "do something"

I am not getting this one right. i am looking for a commandline parser
for my app and lookedup at trallop.
