Overview

Lacci insists on a logging implementation being plugged in before any Shoes object exists. Scarpe ships two (one backed by the logging gem, one simple); Clogs has its own so that a packaged app needs no logging dependency at all.

Configure with SCARPE_LOG_LEVEL (debug/info/warn/error/fatal) or SCARPE_DEBUG=1.
