# This Makefile fragment is meant to be included by packages that
# require a Kerberos 5 implementation.  krb5.buildlink3.mk will:
#
#	* set KRB5BASE to the base directory of the Kerberos 5 files;
#	* set KRB5_TYPE to the Kerberos 5 implementation used.
#
# There are two variables that can be used to tweak the selection of
# the Kerberos 5 implementation:
#
# KRB5_DEFAULT is a user-settable variable whose value is the default
#	Kerberos 5 implementation to use.
#
# KRB5_ACCEPTED is a package-settable list of Kerberos 5 implementations
#	that may be used by the package.
