+dnl @synopsis AX_LIB_ORACLE_OCI([MINIMUM-VERSION])
+dnl
+dnl This macro provides tests of availability of Oracle OCI API
+dnl of particular version or newer.
+dnl This macros checks for Oracle OCI headers and libraries
+dnl and defines compilation flags
+dnl
+dnl Macro supports following options and their values:
+dnl 1) Single-option usage:
+dnl --with-oci - path to ORACLE_HOME directory
+dnl 2) Two-options usage (both options are required):
+dnl --with-oci-include - path to directory with OCI headers
+dnl --with-oci-lib - path to directory with OCI libraries
+dnl
+dnl NOTE: These options described above does not take yes|no values.
+dnl If 'yes' value is passed, then WARNING message will be displayed,
+dnl 'no' value, as well as the --without-oci-* variations will cause
+dnl the macro won't check enything.
+dnl
+dnl This macro calls:
+dnl
+dnl AC_SUBST(ORACLE_OCI_CFLAGS)
+dnl AC_SUBST(ORACLE_OCI_LDFLAGS)
+dnl AC_SUBST(ORACLE_OCI_VERSION)
+dnl
+dnl And sets:

+dnl HAVE_ORACLE_OCI
