description         validate and inspect PNG, JNG and MNG files

long_description    pngcheck verifies the integrity of PNG, JNG and MNG files \

                    (by checking the internal 32-bit CRCs [checksums] and \

                    decompressing the image data)\; it can optionally dump \

                    almost all of the chunk-level information in the image in \

                    human-readable form. For example, it can be used to print \

                    the basic statistics about an image (dimensions, bit \

                    depth, etc.)\; to list the color and transparency info in \

                    its palette (assuming it has one)\; or to extract the \

                    embedded text annotations. This is a command-line program \

                    with batch capabilities.
