# Usage: Generate binary packages by building the Packages project in
# Monodevelop, then execute this script in the Git top directory. Packages for
# the current version will be generated in Packages/. Make sure that the commit
# you have currently checked out corresponds to the version you want to
# generate.
#
# The version number is automatically determined by looking at the
# current commit's annotated tag. The tag must be "va.b.c", where
# a.b.c is the version number. An additional release candidite specifier
# (va.b.c-rd) may be included, where d is a number.
