For each Ruby module/class, we have Ruby methods on the left and the equivalent
Clojure functions and/or relevant notes are on the right.

For clojure functions, symbols indicate existing method definitions, in the 
clojure namespace if none is explicitly given.  clojure.contrib.*/* functions can
be obtained from http://github.com/kevinoneill/clojure-contrib/tree/master,
ruby-to-clojure.*/* functions can be obtained from the source files in this
gist.

If no method symbol is given, we use the following notation:

# Work with Roman numerals just like normal Integers.
class RomanNumeral < Numeric
  include Comparable

  # The largest integer representable as a roman
  # numerable by this module.
  MAX = 3999

  # Taken from O'Reilly's Perl Cookbook 6.23. Regular Expression Grabbag.
  REGEXP = /^M*(D?C{0,3}|C[DM])(L?X{0,3}|X[LC])(V?I{0,3}|I[VX])$/i

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
