API A-Z¶
The TYPO3 APIs are first and foremost documented inside of the source scripts. It would be impossible to maintain documentation at more than one location given the fact that things change and sometimes fast. This chapter describes the most important elements of the API.
Note
The source is the documentation! (General wisdom)
