			"""This function is called after a user has visited a document type's
			"homepage" and selected the type of "action" to perform. Having
			clicked an action-button (e.g. "Submit a New Record"), this function
			will be called . It performs the task of initialising a new submission
			session (retrieving information about the submission, creating a
			working submission-directory, etc), and "drawing" a submission page
			containing the WebSubmit form that the user uses to input the metadata
			to be submitted.
			When a user moves between pages in the submission interface, this
			function is recalled so that it can save the metadata entered into the
			previous page by the user, and draw the current submission-page.

			Note: During a submission, for each page refresh, this function will be
			called while the variable "step" (a form variable, seen by
			websubmit_webinterface, which calls this function) is 0 (ZERO).

			In other words, this function handles the FRONT-END phase of a
			submission, BEFORE the WebSubmit functions are called.

			@param req: (apache request object) *** NOTE: Added into this object, is
			a variable called "form" (req.form). This is added into the object in
			the index function of websubmit_webinterface. It contains a
			"mod_python.util.FieldStorage" instance, that contains the form-fields
			found on the previous submission page.
			@param c: (string), defaulted to CFG_SITE_NAME. The name of the CDS Invenio
			installation.
			@param ln: (string), defaulted to CFG_SITE_LANG. The language in which to
			display the pages.

			submission is being made.
			@param act: (string) - The ID of the action being performed (e.g.
			submission of bibliographic information; modification of bibliographic
			information, etc).
			@param startPg: (integer) - Starting page for the submission? Defaults
			to 1.
			@param indir: (string) - the directory used to store all submissions
			of the given "type" of this submission. For example, if the submission
			is of the type "modify bibliographic information", this variable would
			contain "modify".
			@param access: (string) - the "access" number for the submission
			(e.g. 1174062451_7010). This number is also used as the name for the
			current working submission directory.
			@param mainmenu: (string) - contains the URL (minus the CDS Invenio
