Version script for Cargo Rust projects

bump-version.sh

#!/bin/bash
#
# > make a file executable
# chmod +x ./bump-version.sh
#
# works with a file called VERSION in the current directory,
# the contents of which should be a semantic version number
# such as "v1.2.3"

# 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 CHANGES (under the title of the new version
# number) and create a GIT tag.
