; Dynamic Extensions;

; If you want an extension library to be loaded automatically, use the following syntax:
; extension=modulename.extension
; For example, On Windows,
; extension=msql.dll
; or on UNIX,
; extension=msql.so
; Note that this should only be the name of the module, no directory information is required. inside.
; Use the extension_dir directive above to specify the location of the extension library.
