The important modules for application programmers are:

• Wd_types: Defines the fundamental types

• Wd_dialog: Contains the base class dialog from which the programmer's dialog classes should inherit

• Wd_template: Access to template definitions, including the possibility to instantiate templates and convert them to strings.

• Wd_cycle: Processes a CGI request and computes the response, i.e. this is the entry point to request processing

• Wd_transform: Here are the functions to load the UI file (it mainly contains the transformation engine, but this is hidden)

• Wd_run_cgi: A sample main program for CGI scripts (can be used instead of calling Wd_cycle and Wd_transform directly).

• Wd_run_jserv: A sample main program for JSERV servlets (can be used instead of calling Wd_cycle and Wd_transform directly).
