# To rebuild everything and create the msi installers run:

#   rake rebuild_setup
#
# To rebuild everything and install Git Extensions run:
#
#   rake install
#
# To change the version number of the installer, create a
# git tag with the required number. If the current HEAD does
# not have a tag then git will create a description based on
# the last tag it is able to find in the history.
#
# Git may, for example, describe a version such as 1.91-79-g05ccafd.
# This means that the current HEAD is 79 commits past the 1.91
# release and its hash starts with 05ccafd.
