# Annoyingly, it's not possible to programmatically figure out
# the version from the tag name. Our scheme is:
# VERSION: release: 1.7.0, development opens: 1.7.50,
# rc0 for next release: 1.7.90, rc1: 1.7.91, next release: 2.0.0
# Tag: v<major>.<minor>.<revision>[-rc<rc#>]
# Examples:
#  qemu-tag-release 2.1.90 v2.2.0-rc0
#  qemu-tag-release 2.1.91 v2.2.0-rc1
#  qemu-tag-release 2.2.0 v2.2.0
#  qemu-open-devtree 2.3

# This script doesn't handle the "reopen dev tree" case;
# see qemu-open-devtree for that.
