=head1 NAME
Devel::Cover::Report::Compilation - backend for Devel::Cover
=head1 VERSION
version 1.21
=head1 SYNOPSIS
cover -report compilation
=head1 DESCRIPTION
This module provides a textual reporting mechanism for coverage data.
It is designed to be called from the C<cover> program.
It produces one report per line, in a format like Perl's own compilation error
messages. This makes it easy to, e.g. use Emacs compilation mode to step
through the reports.
