Example fails with missing files

[alexvollmer]

When running the code given in README with the '-f' option and filenames that do not exist, we get incorrect error messages:

[doux] ~/temp: ./clipex.rb -f foo,bar ./clipex.rb -f foo,bar Errors: files: Missing required parameter: files Usage: -s --server The server name (default: localhost) -p --port The port (default: 8080) -f --files Files to send REQUIRED -v --verbose Make it chatty

The error-checking in the block (which raises if the file can't be found) doesn't propagate out to the command-line. As an aside, when the "files" is marked as optional (instead of required) the correct behavior occurs:

[alex] ~: /tmp/foo.rb -f foo,bar Errors: files: unable to read file foo Usage: -s --server The server name (default: localhost) -p --port The port (default: 8080) -f --files Files to send -v --verbose Make it chatty
