# This file determines which Python version is used as a dependency for
# a package.
#
# === User-settable variables ===
#
# PYTHON_VERSION_DEFAULT
# The preferred Python version to use.
#
# Possible values: 27 33 34 35
# Default: 27
#
# === Infrastructure variables ===
#
# PYTHON_VERSION_REQD
# Python version to use. This variable should not be set in
# packages. Normally it is used by bulk build tools.
#
# Possible: ${PYTHON_VERSIONS_ACCEPTED}
# Default: ${PYTHON_VERSION_DEFAULT}
#
# === Package-settable variables ===
#
# PYTHON_VERSIONS_ACCEPTED
# The Python versions that are acceptable for the package. The
# order of the entries matters, since earlier entries are
# preferred over later ones.
#
# Possible values: 35 34 33 27
# Default: 35 34 33 27
#
# PYTHON_VERSIONS_INCOMPATIBLE
# The Python versions that are NOT acceptable for the package.
#
# Possible values: 27 33 34 35
# Default: (empty)
#
# PYTHON_FOR_BUILD_ONLY
# Whether Python is needed only at build time or at run time.
#
# Possible values: yes no tool
# Default: no
#
# PYTHON_SELF_CONFLICT
# If set to "yes", additional CONFLICTS entries are added for
# registering a conflict between pyNN-<modulename> packages.
#
# Possible values: yes no
# Default: no
#
# === Defined variables ===
#
# PYPKGPREFIX
# The prefix to use in PKGNAME for extensions which are meant
# to be installed for multiple Python versions.
#
# Example: py27
#
# PYVERSSUFFIX
# The suffix to executables and in the library path, equal to
# sys.version[0:3].
#
# Example: 2.7
#
# Keywords: python
