dnl This file provides local macros for packages which use specific
dnl external libraries.  The public macros are:
dnl
dnl	ATHENA_UTIL_COM_ERR
dnl		Generates error if com_err not found.
dnl	ATHENA_UTIL_SS
dnl		Generates error if ss not found.
dnl	ATHENA_REGEXP
dnl		Sets REGEX_LIBS if rx library used; ensures POSIX
dnl		regexp support.
dnl	ATHENA_MOTIF
dnl		Sets MOTIF_LIBS and defines HAVE_MOTIF if Motif used.
dnl	ATHENA_MOTIF_REQUIRED
dnl		Generates error if Motif not found.
dnl	ATHENA_AFS
dnl		Sets AFS_LIBS and defines HAVE_AFS if AFS used.  Pass
dnl		in an argument giving the desired AFS libraries;
dnl		AFS_LIBS will be set to that value if AFS is found.
dnl		AFS_DIR will be set to the prefix given.
dnl	ATHENA_AFS_REQUIRED
dnl		Generates error if AFS libraries not found.  AFS_DIR
dnl		will be set to the prefix given.
dnl	ATHENA_KRB4
dnl		Sets KRB4_LIBS and defines HAVE_KRB4 if krb4 used.
dnl	ATHENA_KRB4_REQUIRED
dnl		Generates error if krb4 not found.  Sets KRB4_LIBS
dnl		otherwise.  (Special behavior because krb4 libraries
dnl		may be different if using krb4 compatibility libraries
dnl		from krb5.)
dnl	ATHENA_KRB5
dnl		Sets KRB5_LIBS and defines HAVE_KRB5 if krb5 used.
dnl	ATHENA_KRB5_REQUIRED
dnl		Generates error if krb5 not found.
dnl	ATHENA_HESIOD
dnl		Sets HESIOD_LIBS and defines HAVE_HESIOD if Hesiod
dnl		used.
dnl	ATHENA_HESIOD_REQUIRED
dnl		Generates error if Hesiod not found.
dnl	ATHENA_ARES
dnl		Sets ARES_LIBS and defines HAVE_ARES if libares
dnl		used.
dnl	ATHENA_ARES_REQUIRED
dnl		Generates error if libares not found.
dnl	ATHENA_ZEPHYR
dnl		Sets ZEPHYR_LIBS and defines HAVE_ZEPHYR if zephyr
dnl		used.
dnl	ATHENA_ZEPHYR_REQUIRED
dnl		Generates error if zephyr not found.
dnl
dnl All of the macros may extend CPPFLAGS and LDFLAGS to let the
dnl compiler find the requested libraries.  Put ATHENA_UTIL_COM_ERR
dnl and ATHENA_UTIL_SS before ATHENA_AFS or ATHENA_AFS_REQUIRED; there
dnl is a com_err library in the AFS libraries which requires -lutil.
