Overview

A matcher which matches exceptions which contain a certain file in their backtrace.

app.config.match :backtrace, "my_file"
app.config.match :backtrace, %r{lib/my_application}
app.config.match :backtrace, %r{lib/my_application}, :depth => 5

By default this will search the entire backtrace, unless a depth is specified.
