Bump version shell script.
#!/bin/bash
# Thanks goes to @pete-otaqui for the initial gist:
# https://gist.github.com/pete-otaqui/4188238
#
# Original version modified by Marek Suscak
#
# works with a file called VERSION in the current directory,
# the contents of which should be a semantic version number
# such as "1.2.3" or even "1.2.3-beta+001.ab"
# this script will display the current version, automatically
# suggest a "minor" version update, and ask for input to use
# the suggestion, or a newly entered value.
# once the new version number is determined, the script will
# pull a list of changes from git history, prepend this to
# a file called CHANGELOG.md (under the title of the new version
# number), give user a chance to review and update the changelist
# manually if needed and create a GIT tag.
