Building Flash utilities from Flex Falcon, under Linux

Falcon is the next compiler for the Flex framework. The Flash part has interesting utilities that allow for deep parsing of SWFs. We're going to (partially) build Falcon in order to get the JARs containing the utilities.
It's a tricky process, and involves a 180MB download.

We'll need Git, the JDK, Ant and JFlex, so get them:

sudo apt-get install git openjdk-7-jdk ant jflex

# Get the frequency, in Hertz, from an octave number.
# `0` corresponds to A0, `1` to A1, etc.
frequencyOf = (octaves) ->
  27.5 * Math.pow(2, octaves)

# Parse a note string into its corresponding octave number.
# Note: this cannot parse sharp (#) notes yet.
parseNote = (string) ->
  point = string.charCodeAt(0) - 65
  offset = point * 2

derivative = (coefficients, point, k) ->
  return 0 if k >= coefficients.length
  result = 0
  factor = 1

  # Initial factor (k factorial)
  for i in [1..k]
    factor *= i

  # Calculate result
