# Expressions in rsyslog

Rsyslog supports expressions at a growing number of places. So far, they are supported for filtering messages.

Expression support is provided by RainerScript. Please see the RainerScript documentation for more details.

C-like comments (/* some comment */) are supported inside the expression, but not yet in the rest of the configuration file.
