+
+  use Games::NES::SpriteMaker;

+  my $chr = Games::NES::SpriteMaker::image_to_sprite('spritemap.pgm');
+  $fh->print($chr);

+
+=head1 DESCRIPTION
+
+This module contains useful functions for manipulating images in the PNM format
+in order to create and modify sprite data (CHR-ROM banks) in NES roms. The idea
+is that drawing sprites is much easier in a real graphics editor, and then you
+can save the image as a .pbm/.pgm/.ppm file and convert it into sprite data
+directly, rather than having to edit sprites in a hex editor.
+
+Right now, the capabilities are pretty limited, but I'm open to adding more
+functionality as it becomes useful.

+=func image_to_sprite($data, %opts)
+
+Converts PNM data to CHR-ROM data. C<$data> can either be a filename or a
+scalar reference which is a reference to a string containing PNM-format data.
+C<%opts> is a hash of options for how to generate the data. Currently the only
+option is C<rom_size>, which determines the size of the .chr file to generate.
+It defaults to C<8192>.
