There's no manpage included in this package. Please fix! Reproducible: Always
Which one do you expect.
maybe one that helps you with the configuration?
This package doesn't have a man page, but it has a README and a default configuration file that goes through all parameters squidclamav supports. Also the emerge process itself tells you how to plug in squidclamav into squid. If you're not happy with that, take it to upstream. Closed as UPSTREAM.
