# 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.
#
# User-settable variables:
#
# KRB5_DEFAULT
#	The default Kerberos 5 implementation to use.
#
#	Possible values: heimdal mit-krb5
#
# Package-settable variables:
#
# KRB5_ACCEPTED
#	The list of Kerberos 5 implementations that can be used by the
#	package.
#
#	Possible values: (see KRB5_DEFAULT)
#
# Keywords: kerberos heimdal krb krb5 mit-krb5
