#!/usr/bin/env bash
# prepares a template e-mail and HTML file to announce a new release
# Copyright (c) 2006-2016 Willy Tarreau <w@1wt.eu>
#
# In short :
# - requires git
# - wants that last commit is a release/tag
# - no restriction to master, uses last tag
# - creates mail-$version.txt
# - creates web-$version.html
# - indicates how to edit the mail and how to send it
USAGE="Usage: ${0##*/} [-f] [-p] [-b branch] [-d date] [-o oldver] [-n newver]
-f: force to overwrite existing files and ignore local changes
-p: prepare future release (skip branch and tags existence checks)
-b: force the project branch name to this (def: inherited from the version)
-d: force the release date (e.g. to rework a failed announce)
-o: previous version (def: newver-1)
-n: new version (if not last tag)
