+=head1 NAME
+
+Lintian::Processable::Fields::Files - Lintian interface to .buildinfo or changes file data collection
+
+=head1 SYNOPSIS
+
+   use Moo;
+
+   with 'Lintian::Processable::Fields::Files';
+
+=head1 DESCRIPTION
+
+Lintian::Processable::Fields::Files provides an interface to data for .buildinfo
+and changes files.  It implements data collection methods specific to .buildinfo
+and changes files.
+
+=head1 INSTANCE METHODS
+
+=over 4
+
+=item files
+
+Returns a reference to a hash containing information about files listed
+in the .buildinfo file.  Each hash may have the following keys:
+
+=over 4
+
+=item name
+
+Name of the file.
+
+=item size
+
+The size of the file in bytes.
+
+=item section
+
+The archive section to which the file belongs.
+
+=item priority
+
+The priority of the file.
+
+=item checksums
+
+A hash with the keys being checksum algorithms and the values themselves being
+hashes containing
+
+=over 4
+
+=item sum
+
+The result of applying the given algorithm to the file.
+
+=item filesize
+
+The size of the file as given in the .buildinfo section relating to the given
+checksum.
