# Example: If you put your dev IPKs at mojocoder.example.com/dev,
# your latest app is called foobar, and you're at version 0.5.0, you 
# should set:
#
# MY_HOSTNAME=mojocoder.example.com
# STDPATH=dev\\/com.example.mojocoder
# STDVERSION=0.5.0
#
# Then "./homebrew.sh my foobar" will try to download:
# http://mojocoder.example.com/dev/com.example.mojocoder.foobar_0.5.0_all.ipk
