Suggested by Yann Thierry-Mieg. * iface/dve2/dve2.cc (convert_aps): Allow string on the right of operators, and look them up. * iface/dve2/dve2check.test: Test this syntax.
* iface/dve2/defs.in, iface/dve2/dve2check.test, iface/dve2/beem-peterson.4.dve: New files. * iface/dve2/Makefile.am: Add them. * configure.ac: Generate iface/dve2/defs.
