Is it possible to publish a product manual with text, images, tables, links and video using the ShiVa authoring tool?
Shiva Authoring tool is mainly used to compile projects generated by ShiVa Editor into executable applications and although documentation word is used on developer's website I am afraid you can't export manuals. You could try to create a manual with all the things you need by using a PDF creation software like : Acrobat X Pro.
