[TYPO3-dev] Howto Debug my extensions

[Helmut Hummel]

Hello,
can anyone of you point out a dokument where I can read what
possibilities there are in TYPO3 to debug an extension (db-queries,
debug output, etc.)? I heard about syslog and devlog but I'm not sure
how to use them.

Until now I do my debugging with pure echo statements, but I want to
change to any already existing framework for that.

Thanks a lot

Helmut
