[TYPO3] Searching for a hook

[Sascha Mantscheff]

I'd like to enrich the text content of my application by links from a 
separate table (similar to a glossary).
I found the hook 
TYPO3_CONF_VARS['SC_OPTIONS']['tslib/class.tslib_fe.php']['contentPostProc-output'] 
and I could scan the complete HTML output for text chunks which might be 
transformed into links. But I wonder if there is a hook which is nearer 
at the tt_content table so that I don't have to analyze the whole HTML 
output for inserting my links.
