#
# Helper script to build a deb package for MXNet
#
# This script provides some custom handling of git tags to allow us to tag
# package releases with well-crafted Debian package versions, e.g.:
#
#     1.0.0-0tsunami1
#
# where `1.0.0` is the upstream MXNet version, and `0tsunami1` is the package
# iteration -- in this case following the `debian_revision` format where the
# initial 0 indicates that we are not forking any upstream Debian package, the
# `tsunami` identifies Sociomantic Tsunami as the packager, and the last number
# corresponds to our package revision (1, 2, 3, ..., restarting from 1 every
# time the upstream version changes).
#
# This script parses the tag and separates out the upstream version and package
# iteration, appending dirty-build and distro-code details to the latter, before
# invoking Makd's package-building functionality with this version information
# specified.
