Push.ps1

param([switch]$Force)

# This script ensures that we abort pushing if we have unfinzalied Mercurial patches.
#
# hg-git has bug that will break the local repository if we do all the following things:
#	1. we push changes in A.patch to Github without finalizing the patch first
#	2. we make further changes to the patch locally and refresh
#	3. we finalize and push A.patch to Github again
#
# Other requirements so that this script work:
#
# 	1. bb must be defined under [paths] in .hg/hgrc
# 	2. git must be defined under [paths] in .hg/hgrc
# 	3. 'push' must be disabled under [alias] in .hg/hgrc
