NAME
	$program - Make a release

SYNOPSIS
	$program [OPTIONS] VERSION

DESCRIPTION

	Do the sequence of actions necessary to properly produce a release
	branch. This includes updating the project version and committing that
	to the repository, creating a release tag and a release branch if
	needed, and updating the project version again to indicate that any
	further commits are development work. Requires 1 argument: the VERSION
	number (e.g., 1.23).

	The script uses svn info to retrieve information about the repository
	and path of the current directory, and inspects that to determine
	exactly what to do. If the current path relative to the repository root
	starts with 'trunk', then a new branch is created named
	branch/\$VERSION. If the current path starts with something else 
	than 'trunk', it is assumed to be a working branch, and no new branch is
	created. In either case, a copy of the current working copy is created
	in tags/\$VERSION.

Hi,

This is an automatic notification about a new datatracker release, 
v$VER, generated when running the mkrelease script.

Release notes:

$changes

The new version is available for installation through SVN checkout, with
  'svn checkout http://svn.tools.ietf.org/svn/tools/$PROJ/tags/$VER'

For development, check out the new development version instead:
  'svn checkout http://svn.tools.ietf.org/svn/tools/$PROJ/tags/dev/$DEV'
