# This file contains some routines to interact with different databases, such
# as MySQL and Berkley DB.  To include this file, define macro
# USE_[DATABASE], for example USE_MYSQL.  Defining macro like
# USE_[DATABASE]_VER or WANT_[DATABASE]_VER will include this file as well.
#
##
# USE_MYSQL		- Add MySQL (client/server/embedded) dependency (default:
#			  client).
#			  If no version is given (by the maintainer via the port or
#			  by the user via defined variable), try to find the
#			  currently installed version.  Fall back to default if
#			  necessary (MySQL-5.6 = 56).
# DEFAULT_MYSQL_VER
#			- MySQL default version.  Can be overridden within a port.
#			  Default: 56.
# WANT_MYSQL_VER
#			- Maintainer can set an arbitrary version of MySQL to always
#			  build this port with (overrides WITH_MYSQL_VER).
# IGNORE_WITH_MYSQL
#			- This variable can be defined if the ports does not support
#			  one or more versions of MySQL.
# WITH_MYSQL_VER
#			- User defined variable to set MySQL version.
# MYSQL_VER
#			- Detected MySQL version.
##
# USE_BDB	- Add Berkeley DB library dependency.
#			  If no version is given (by the maintainer via the port or
#			  by the user via defined variable), try to find the
#			  currently installed version.  Fall back to default if
#			  necessary (db5 if compatible).
#			  This adds a "debug-bdb" make target which will dump the
#			  related data.
# INVALID_BDB_VER
#			- This variable can be defined when the port does not
#			  support one or more versions of Berkeley DB.
# WANT_BDB_VER
#			- Maintainer can set a version of Berkeley DB to always
#			  build this port with (overrides WITH_BDB_VER).
# WITH_BDB_VER
#			- User defined global variable to set Berkeley DB version.
# <BDB_UNIQUENAME>_WITH_BDB_VER
#			- User defined port specific variable to set Berkeley DB
#			  version.
# WITH_BDB_HIGHEST
#			- Use the highest installed version of Berkeley DB.
# WITH_BDB6_PERMITTED
# 			- If defined, BerkeleyDB 6 is added to the
# 			  default version set, making it eligible even
# 			  if not already installed. This is due to its
# 			  stricter Affero GNU Public License.
#
# These variables will then be filled in by this .mk file:
#
# BDB_LIB_NAME
#			- This variable is automatically set to the name of the
#			  Berkeley DB library (default: db41).
# BDB_LIB_CXX_NAME
#			- This variable is automatically set to the name of the
#			  Berkeley DB C++ library (default: db41_cxx).
# BDB_INCLUDE_DIR
#			- This variable is automatically set to the location of
#			  the Berkeley DB include directory (default:
#			  ${LOCALBASE}/include/db41).
# BDB_LIB_DIR
#			- This variable is automatically set to the location of
#			  the Berkeley DB library directory.
# BDB_VER
#			- Detected Berkeley DB version.
##
# USE_SQLITE		- Add dependency on SQLite library.  Valid values are:
#			  3 and 2.  If version is not specified directly then
#			  SQLite-3 is used (if USE_SQLITE= yes).
# SQLITE_VER
#			- Detected SQLite version.
##
# USE_FIREBIRD		- Add dependency on Firebird library.  Valid values are:
#			  2 and 1.  If no version is given by the maintainer (if
#			  USE_FIREBIRD= yes) and the user did not define
#			  WITH_FIREBIRD_VER variable, fall back to default "2".
# WITH_FIREBIRD_VER
#			- User defined variable to set Firebird version.
# FIREBIRD_VER
#			- Detected Firebird version.
