[TYPO3-english] builduing a correct tt_news single link

[Lina Wolf]

tt_news has many, many ways to configure the building links for the single 
view. It may or may not contain dates or categories. sometimes the single 
view pid is configured by caegory, with or without backpid etc.

If I want to create a link to the tt_news single view from another 
extension, how can I create a correct tt_news link.
