+NAME
+	$program - Make a release
+
+SYNOPSIS
+	$program [OPTIONS] VERSION
+
+DESCRIPTION
+
+	Do the sequence of actions necesary 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.
