Logger Additivity

The article says on page 3:

Each appender carries an additivity flag. If this is set to a false value, like in $appender->additivity(0); then the message won't bubble up further in the hierarchy after the appender is finished.

This is incorrect, appenders don't carry an additivity flag, only loggers do. Please replace appender in the above paragrph by logger and it makes sense.

Thanks to Dave Weber for pointing this out.

Typos

has has (in first para in Logger Categories)
sentence before "Compact Logger Setups with Configuration Files" loggers don't have thresholds - they have levels
appenders have thresholds
2nd para in the above section whichs -> whose
Typical Use Cases descendents -> descendants (it was spelled right once)
Performance Penalties negligable -> negligible

Thanks to Jon Bjornstad for pointing this out.
