# define the default versions
MODPY_DEFAULT_VERSION_2 = 2.7
MODPY_DEFAULT_VERSION_3 = 3.8

# If switching to a new MODPY_DEFAULT_VERSION_3:
# - In the old default version, @comment the non-suffixed bin/XXX files (python3,
#   pydoc3, idle3, etc), lib/pkgconfig/python3.pc, and man/man1/python3.1 and
#   bump REVISION
# - In the new version, un-@comment these same files
# - In the new version, @conflict on the old REVISION of the old version
#   (3.6.8p1 was "default py3 is py3.6", 3.6.8p2 was after the switch to "default
#   is py3.7", so the 3.7 ports had @conflict python-subpkg-<3.6.8p2)

# If later *removing* an old version:
# - *move* the numbered @conflict python-*->=3.2,<3.7 to the new version
#   and update e.g. to  @conflict python-*->=3.2,<3.8
# - *move* the @pkgpath markers to the new version and add a new one for
#   the old version you have just retired.

# In all cases:
# - keep the @conflict python-*-${VERSION_SPEC} PLIST lines as-is, they are
#   there to override the "@option no-default-conflict" and set automatically
#   from the variable defined in 3.x/Makefile.

# Also note:
# - Some subpackages e.g. -idle have a conflict on an old version of the main
#   package e.g. "@conflict python->=3.6,<3.6.8p0", this is due to a file
#   moving between subpackages in the past.
