it's like follows, and it's again needed for the upcoming autoloader:

t3lib_Singleton
t3lib_cache_CacheManager
tx_myext_controller_MyController
tx_myext_someotherfolder_somesubfolder_TheClassInThatFolder

... the last "word" is always upper camel case

For existing classes: They stay as they are for compatability reasons 
and are considered "exceptions"

P.S.

The prvious examples would translate to the following paths/files:

t3lib/interfaces/interface.t3lib_singleton.php (special, but defined, 
case for interfaces)
t3lib/cache/class.t3lib_cache_cachemanager.php
ext/myext/controller/class.tx_myext_controller_mycontroller.php
ext/myext/someotherfolder/somesubfolder/class.tx_myext_someotherfolder_somesubfolder_theclassinthatfolder.php
