# Variation on Hashrocket's script for managing the git process
# as documented here: http://reinh.com/blog/2008/08/27/hack-and-and-ship.html
# Create shell scripts out of each of these, put them in your path (~/bin for example)
# chmod 755 them and use like this:
#
# This version of hack is totally different than Hackrockets. I feel that hack implies 
# that you are getting started, not finishing up. sink is Hashrockets hack.

# $ hack branch_name

# Assume a pool of N different investors, each investing in D deals,

# Randomly simulate each investor's total payoff, then compute the

# This gives an individual angel an idea of what kind of payoff &
