Some library methods are stored in the ruby.rb file, with shortcuts to read a
map block, find an unit or an item, etc.
Global objects are stored in the GlobalObjects class ; each object accessor is
mirrored as a DFHack module method (eg df.world).
Global objects are accessible through the 'df' accessor (eg df.world).
The ruby plugin defines 2 dfhack console commands:
rb_load <filename> ; load a ruby script. Ex: rb_load hack/plants.rb (no quotes)

You can use single-quotes for strings ; avoid double-quotes that are parsed
and removed by the dfhack console.
If dfhack reports 'rb_eval is not a recognized command', check stderr.log. You
need a valid 32-bit ruby library to work, and ruby1.8 is prefered (ruby1.9 may
crash DF on startup for now). Install the library in the df root folder (or
hack/ on linux), the library should be named 'libruby.dll' (.so on linux).
You can download a tested version at http://github.com/jjyg/dfhack/downloads/
The plugin also interfaces with dfhack 'onupdate' hook.
To register ruby code to be run every graphic frame, use:
handle = df.onupdate_register { puts 'i love flooding the console' }
