+The libmng library supports decoding, displaying, encoding, and various other
+manipulations of Multiple-image Network Graphics (MNG) format image files.  It
+uses the zlib(3) compression library, and optionally the JPEG library by the
+Independant JPEG Group (IJG) and/or lcms (little CMS), a color-management
+library by Marti Maria Saguar.
