if a port needs 2.x then set MODPY_VERSION=${MODPY_DEFAULT_VERSION_2}.
This commit doesn't change any versions currently used; it may be that
some ports have MODPY_DEFAULT_VERSION_2 but don't require it, those
should be cleaned up in the course of updating ports where possible.
Python module ports providing py3-* packages should still use
FLAVOR=python3 so that we don't have a mixture of dependencies some
using ${MODPY_FLAVOR} and others not.
Ophis is a cross-assembler for the 65xx series of chips. It supports
the stock 6502 opcodes, the 65c02 extensions, and syntax for the
"undocumented opcodes" in the 6510 chip used on the Commodore 64.
(Syntax for these opcodes matches those given in the VICE team's
documentation.)
