Ldoce Ruby Gem:
Easily interface with the Longman Dictionary of Contemporary English API from Ruby:
NB currently mac only as it depends on the afplay command.

Ldoce passes an mp3 url to commandline for audio output of the pronunciation of a dictonary word:
If the URL or filename for the mp3 files contain shell metacharacters code can be executed remotely as the client:
[./ldoce-0.0.2/lib/ldoce/word.rb]
if mp3?
unless File.exists? filename
command = "curl #{mp3_url} -silent > {filename}"
`{command}`
end
`afplay #{filename}`
end
