# original version modified for pidrone_pkg releases

# 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 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.
