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_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_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.
