# PYTHON_COMPAT can be either a scalar or an array. If it's a scalar,

+# @DEFAULT_UNSET
+# @DESCRIPTION:
+# The list of USEflags required to be enabled on the chosen Python
+# implementations, formed as a USE-dependency string. It should be valid
+# for all implementations in PYTHON_COMPAT, so it may be necessary to
+# use USE defaults.
+#
+# Example:
+# @CODE
+# PYTHON_COMPAT_USE="gdbm,ncurses(-)?"
+# @CODE
+#
+# Will cause the Python dependencies to look like:
+# @CODE
+# python_targets_pythonX_Y? (
+# dev-lang/python:X_Y[gdbm,ncurses(-)?] )
+# @CODE
+
# @ECLASS-VARIABLE: PYTHON_DEPS
# @DESCRIPTION:
# This is an eclass-generated Python dependency string for all
