Bash script to bump the version
#!/bin/bash
# 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"
# this script will display the current version, automatically
# suggest a "minor" version update, and ask for input to use
# the suggestion, or use a newly entered value.
