[TYPO3] where is each extension used?

in localconf.php you only can see whether an extension is installed.
each extension existing in .../typo3conf/ext but not mentioned in 
localconf.php is available but not installed. This you can see also in 
the extensionmanager view: 'install extension': these extension got 
another icon than the installed.

but you don't know whether an extension is installed but not used. I 
think this was the question of Bing Du.

and this can be a very delicate question. You can use an extension in 
very differnt ways.
* just include as library for other extensions
* FE-plugin
* BE-plugin
* just database enhancement
     :
(see kickstarter for some more options)

with FE-plugins you have a chance (not 100%!)
if you look in the object-browser you can search for the extension-key 
(press search-button twice!)

if the extensionkey appears the extension is configured to be used. it 
may be not used anyway.

another approach: have a look in the table tt_content and select all 
records containing a value in the field plugin.
deselect hidden and deleted records and you know about some extensions 
which are realy used. (here you see the plugin-name not the extension key)

that's all like: try to deinstall the extension and look whether your 
page continue running. (trial and error)
