gnucap-ruby bindings

I'm creating ruby bindings for gnucap.
The source will be available on rubyforge as soon as I have an account 
created.
This is just an experimental phase and I would appreciate any 
suggestions, comments, ...

These are the basic commands:

command: Send a command to gnucap and return the output as a string
buildcmd: Send a command in build mode and return the output as a string
analysis: Send a command and return the output as a Hash

I use pipes to communicate to gnucap in interactive mode.

example:

gnucap = Sim::Gnucap.new("Bridge")
gnucap.buildcmd("v1 1 0 sin(0 15 60 0 0)")
gnucap.buildcmd("rload 2 3 10k")
gnucap.buildcmd("d1 1 2 mod1")
gnucap.buildcmd("d2 0 2 mod1")
gnucap.buildcmd("d3 3 1 mod1")
gnucap.buildcmd("d4 3 0 mod1")
gnucap.buildcmd(".model mod1 d")
gnucap.command("print tran v(1,0) v(2,3)")
plotdata = gnucap.analysis("tran .5m 25m")
...
