Modules

WebL includes a number of standard modules for the convenient reuse of often required functionality. The purpose of this chapter is to introduce the more common modules shipped with the WebL installation (See Standard WebL Modules). To use most of these modules, a programmer must import the module and refer to the exported variables of the module. See Modules
