#
# This Makefile fragment is meant to be included by packages that
# require a FAM implementation.  fam.buildlink3.mk will:
#
#	* set FAMBASE to the base directory of the FAM files;
#	* set FAM_TYPE to the FAM implementation used.
#
# There are three variables that can be used to tweak the selection of
# the FAM implementation:
#
# FAM_DEFAULT is a user-settable variable whose value is the default
#	FAM implementation to use.
#
# FAM_ACCEPTED is a package-settable list of FAM implementations that
#	may be used by the package.
#
# FAM_SERVER is a package-settable flag whose value determines whether
#	or not the server and library are both required.
