The entry point into Launchy. This is the sole supported public API.
Launchy.open( uri, options = {} )
The currently defined global options are:
:debug Turn on debugging output :application Explicitly state what application class is going to be used :host_os Explicitly state what host operating system to pretend to be :ruby_engine Explicitly state what ruby engine to pretend to be under :dry_run Do nothing and print the command that would be executed on $stdout
Other options may be used, and those will be passed directly to the application class
