# SYNOPSIS
#
#   AX_DIST_RPM([SPEC])
#
# DESCRIPTION
#
#   Adds support for a rpm dist target.

#   and the Changelog. Use @PACKAGE@ and @VERSION@ to refer to the package
#   name and version respectively.  The files and ChangeLog will be filled
#   in automatically. For instance:
#
#     Summary: Foobar
