OK.  This is not good.  If I try to use require_relative I discover that 
backtracks in the directory tree are ignored.  For instance, given this 
code:

#!/usr/bin/env ruby

lib_path = File.dirname(__FILE__) + '/../lib/forex/hll_forex_ca_feed'
puts lib_path
puts("Library file found? " + (File.file?(lib_path + '.rb')).to_s)
require_relative lib_path
HLLForexCAFeed::Main.new(ARGV).execute

I would expect that the file ./bin/../lib/forex/hll_forex_ca_feed.rb 
would be found.  Instead, when I run this program I see this:

$ bin/forex

bin/../lib/forex/hll_forex_ca_feed
Library file found? true

bin/forex:9:in `require_relative': no such file to load -- 
/home/byrnejb/Software/Development/Projects/proforma.git/bin/lib/forex/hll_forex_ca_feed 
(LoadError) from bin/forex:9:in `<main>

Note that the path determined by require_relative:

home/byrnejb/Software/Development/Projects/proforma.git/bin/lib/forex/hll_forex_ca_feed)

does not accommodate the /../  portion of the relative path provided. 
It simply discards it.

In my opinion, the path should read:

home/byrnejb/Software/Development/Projects/proforma.git/lib/forex/hll_forex_ca_feed

or

home/byrnejb/Software/Development/Projects/proforma.git/bin/../lib/forex/hll_forex_ca_feed

Is this intended behaviour?
