   3 # This file determines which Python version is used as a dependency for
   4 # a package.
   5 #
   6 # === User-settable variables ===
   7 #
   8 # PYTHON_VERSION_DEFAULT
   9 #       The preferred Python version to use.
  10 #
  11 #       Possible values: 25 26 27 31 32
  12 #       Default: 27
  13 #
  14 # PYTHON_VERSION_REQD
  15 #       Python version to use. This is a user variable and
  16 #       should not be set in packages.
  17 #       Normally it is used by bulk build tools.
  18 #
  19 #       Possible: ${PYTHON_VERSIONS_ACCEPTED}
  20 #       Default:  ${PYTHON_VERSION_DEFAULT}
  21 #
  22 # === Package-settable variables ===
  23 #
  24 # PYTHON_VERSIONS_ACCEPTED
  25 #       The Python versions that are acceptable for the package. The
  26 #       order of the entries matters, since earlier entries are
  27 #       preferred over later ones.
  28 #
  29 #       Possible values: 32 31 27 26 25
  30 #       Default: (32 31) 27 26 25
  31 #
  32 # PYTHON_VERSIONS_INCLUDE_3X
  33 #       Wether the default PYTHON_VERSIONS_ACCEPTED should include
  34 #       3.x versions for for this package or not.
  35 #       This variable must be set before including bsd.prefs.mk.
  36 #
  37 #       Possible values: yes no
  38 #       Default: no
  39 #
  40 # PYTHON_VERSIONS_INCOMPATIBLE
  41 #       The Python versions that are NOT acceptable for the package.
  42 #
  43 #       Possible values: 25 26 27 31 32
  44 #       Default: (depends on the platform)
  45 #
  46 # PYTHON_FOR_BUILD_ONLY
  47 #       Whether Python is needed only at build time or at run time.
  48 #
  49 #       Possible values: (defined) (undefined)
  50 #       Default: (undefined)
  51 #
  52 # === Defined variables ===
  53 #
  54 # PYPKGPREFIX
  55 #       The prefix to use in PKGNAME for extensions which are meant
  56 #       to be installed for multiple Python versions.
  57 #
  58 #       Example: py27
  59 #
  60 # PYVERSSUFFIX
  61 #       The suffix to executables and in the library path, equal to
  62 #       sys.version[0:3].
