# This file contains some routines to interact with different databases, such
# as mysql, postgresql and berkley DB. For including this file define macro
# USE_[DATABASE], for example USE_MYSQL. Defining macro like USE_[DATABASE]_VER
# or WANT_[DATABSE]_VER will include this file too.
#
##
# USE_MYSQL		- Add MySQL client 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 (MySQL4.1 = 41).
# DEFAULT_MYSQL_VER
#				- MySQL default version. Can be overriden within a port.
#				  Default: 41.
# WANT_MYSQL_VER
#				- Maintainer can set an arbitrary version of MySQL by using it.
# BROKEN_WITH_MYSQL
#				- This variable can be defined if the ports doesn't support
#				  one or more version of MySQL.
# WITH_MYSQL_VER
#				- User defined variable to set MySQL version.
# MYSQL_VER
#				- Detected MySQL version.
##
# USE_PGSQL		- Add PostgreSQL client 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 (PostgreSQL-7.4 = 74).
# DEFAULT_PGSQL_VER
#				- PostgreSQL default version. Can be overridden within a port.
#				  Default: 74.
# WANT_PGSQL_VER
#				- Maintainer can set an arbitrary version of PostgreSQL by
#				  using it.
# BROKEN_WITH_PGSQL
#				- This variable can be defined if the ports doesn't support
#				  one or more versions of PostgreSQL.
# PGSQL_VER
#				- Detected PostgreSQL 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 (db41+).
# INVALID_BDB_VER	- This variable can be defined when the port doesn't
#			  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
# <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
# 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
#				  sqlite3 is used (if USE_SQLITE= yes).
# SQLITE_VER		- Detected sqlite version.
