-These functions build the foundation for accessing Berkeley DB style
-databases.
-
-This is a general abstraction layer for several file-based databases. As
-such, functionality is limited to a common subset of features supported
-by modern databases such as Sleepycat Software's DB2. (This is not to be
-confused with IBM's DB2 software, which is supported through the ODBC
-functions.)
-
-This extensions allows to work with the following databases:
-dbm      DBM is the oldest (original) type of Berkeley DB style databases.
-         You should avoid it, if possible. We do not support the
-         compatibility functions built into DB2 and gdbm, because they are
-         only compatible on the source code level, but cannot handle the
-         original dbm format.
-ndbm     NDBM is a newer type and more flexible than dbm. It still has
-         most of the arbitrary limits of dbm (therefore it is deprecated).
-gdbm     GDBM is the GNU database manager.
-db2      DB2 is Sleepycat Software's DB2. It's described as "a programmatic
-         toolkit that provides high-performance built-in database support
-         for both standalone and client/server applications.
-db3      DB3 is Sleepycat Software's DB3.
-db4      DB4 is Sleepycat Software's DB4. This is available since PHP 5.0.
-cdb      CDB is "a fast, reliable, lightweight package for creating and
-         reading constant databases." It is from the author of qmail and
-         can be found at http://cr.yp.to/cdb.html. Since it is constant,
-         we support only reading operations. And since PHP 4.3.0 we support
-         writing (not updating) through the internal cdb library.
-cdb_make Since PHP 4.3.0 we support creation (not updating) of cdb files
-         when the bundled cdb library is used.
-flatfile This is available since PHP 4.3.0 for compatibility with the
-         deprecated dbm extension only and should be avoided. However you
-         may use this where files were created in this format. That happens
-         when configure could not find any external library.
-inifile  This is available since PHP 4.3.3 to be able to modify php.ini
-         files from within PHP scripts. When working with ini files you
-         can pass arrays of the form array(0=>group,1=>value_name) or
-         strings of the form "[group]value_name" where group is optional.
-         As the functions dba_firstkey() and dba_nextkey() return string
-         representations of the key there is a new function dba_key_split()
-         available since PHP 5 which allows to convert the string keys into
-         array keys without losing FALSE.
-qdbm     This is available since PHP 5.0.0. The qdbm library can be loaded
-         from http://qdbm.sourceforge.net.
-
-
-After configuring and compiling PHP you must execute the following test
-from commandline:
-  php run-tests.php ext/dba.
-This shows whether your combination of handlers works. Most problematic
-are dbm and ndbm which conflict with many installations. The reason for
-this is that on several systems these libraries are part of more than one
-other library. The configuration test only prevents you from configuring
-malfaunctioning single handlers but not combinations.
