+If C<DBIC_TRACE_PROFILE> is set, L<DBIx::Class::Storage::PrettyPrint>
+will be used to format the output from C<DBIC_TRACE>.  The value it
+is set to is the C<profile> that it will be used.  If the value is a
+filename the file is read with L<Config::Any> and the results are
+used as the configuration for tracing.  See L<SQL::Abstract::Tree/new>
