# Extracts the necessary bits from the Xcode 6.2 (Xcode_6.2.dmg,
# md5sum fe4c6c99182668cf14bfa5703bedeed6) and the Command Line 
# Tools for Xcode 6.2 (10.9: commandlinetoolsosx10.9forxcode6.2.dmg, 
# 10.10: commandlinetoolsosx10.10forxcode6.2.dmg).
#
# This script allows extracting the tools on systems where the command line 
# tools refuse to install due to version checks.
