# Example:
|

# /bin/bash ./ci-git-tag-compared-to-release.sh

|
|
# Description:
|
|
# This script isn't intended to be run standalone but within a Jenkins CI shell execution block
|
|
# It gets a release number from an external service (you'd have to one, otherwise this script is useless to you)
|
|
# It then checks the current git tag to see if it's larger than the 'release' number
|
|
# If it is then it'll go ahead and build a new 'release'
|
|
# It's purpose is to prevent builds occuring for simple README style changes within a GitHub repository
