+=head1 NAME
+
+Perl::Critic::Policy::ValuesAndExpressions::ProhibitImplicitNewlines - Use concatenation or HEREDOCs instead of literal line breaks in strings.
+
+=head1 AFFILIATION
+
+This Policy is part of the core L<Perl::Critic> distribution.
+
+
+=head1 DESCRIPTION
+
+Strings with embedded line breaks are hard to read. Use concatenation
+or HEREDOCs instead.
+
+ my $foo = "Line one is quite long
+ Line two"; # Bad
+
+ my $foo = "Line one is quite long\nLine two"; # Better, but still hard to read
+
+ my $foo = "Line one is quite long\n"
+ . "Line two"; # Better still
+
+ my $foo = <<'EOF'; # Use heredoc for longer passages
+ Line one is quite long
+ Line two
+ Line three breaks the camel's back
+ EOF
+
+
+=head1 CONFIGURATION
+
+This Policy is not configurable except for the standard options.
