Hello ,
As I can't find a useful vbulletin 5 developer documentation anywhere , I was trying to learn it by reverse engineering some of the few products available here on vb.org
on some products .. I can see the product XML file have it's own pages /routes /widgets

<routes>
		<route guid="">
			<regex></regex>
			<class></class>
			<arguments></arguments>
			<product></product>
		</route>
</routes>

and widget

<widgets>
		<widget guid="">
			<template></template>
			<icon></icon>
			<isthirdparty></isthirdparty>
			<category></category>
			<cloneable></cloneable>
			<canbemultiple></canbemultiple>
			<product></product>
			<definitions>
				<definition>
					<field></field>
					<name></name>
					<defaultvalue></defaultvalue>
					<isusereditable></isusereditable>
					<isrequired></isrequired>
					<displayorder></displayorder>
					<validationtype></validationtype>
					<product></product>
				</definition>
			</definitions>
		</widget>
</widgets>

and pages

<pages>
		<page guid="">
			<title></title>
			<metadescription></metadescription>
			<moderatorid></moderatorid>
			<displayorder></displayorder>
			<pagetype></pagetype>
			<product></product>
			<parentGuid></parentGuid>
			<pageTemplateGuid></pageTemplateGuid>
			<routeGuid></routeGuid>
		</page>
</pages>

Where can I create pages/widgets/routes/pagetemplates and assign them to a product like we do with settings/phrases/hooks/templates ?
Thanks!
