+# 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.
