# 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)
