# Easy Versioning in git:
#
# for setting your Version in git use e.g.:
# git tag -a v0.5 -m 'Version 0.5'
#
# Push tags upstream—this is not done by default:
# git push --tags
#
# # in case of a wrong tag remove it:
# git tag -d v0.5
#
# delete remote tag (eg, GitHub version)
# git push origin :refs/tags/v0.5
#
# Then use the describe command:
#
# git describe --tags --long
# This gives you a string of the format:
# 
# v0.5-0-gdeadbee
# ^    ^ ^^
# |    | ||
# |    | |'-- SHA of HEAD (first seven chars)
# |    | '-- "g" is for git
# |    '---- number of commits since last tag
# |
# '--------- last tag
#
# run this script to (re)place Version number in files
