My solution is at [http://rubyurl.com//iFW](http://rubyurl.com//iFW). Sean, Craig Buchek and I  
hacked on this last night at the weekly StL.rb hacking night as our  
topic. As you can see Sean took a Ruby Golf approach, while I took the  
exact opposite approach. I tried to make mine fairly feature rich w/o  
a lot of extra baggage.

It can do the following:  
Take long or short option names  
-h, --help prints the usage statement via RDoc::usage (reads the  
comments at the head of the file : paste.rb)  
-t allows putting text or code on the command line (I.e. --text  
‘puts “hello world”’ )  
Reads options from a YAML config file: ~/.paste.yml. This can be  
expanded to work with nopaste or [rpaste.com](http://rpaste.com), each having different  
form parameters.  
Defaults to Ruby for the lang.

Currently, there is no option for tab expansion, but you can put it in  
the .paste.yml file. Seriously needs a lot of refactoring, esp around  
the response handling and the initial options gathering.

I found it interesting the different ways of handling errors from the  
HTTPResponse in the other quiz answers. Sean wanted to take the best  
of these and maybe create a RubyForge project.

Lots of fun!
