PathList

A PathList is an array containing 1..n paths. It is useful to regroup paths and make lookups on them.

Usage

 path = PathList.new(ENV['PATH'])
 path.find 'env'            #=> "/usr/bin/env"

 # This is already done when including the library
 $:.class                   #=> Array
 $:.extend PathList::Finder
 $:.find_ext = 'rb'

 $:.find 'uri'              #=> "/usr/lib/ruby/1.8/uri.rb"
