DESCRIPTION
The main purpose of this utility is to recompress png files to get the smallest possible size.Please note that this utility is not able to read a generic file. Itcqs granted to be able to read only the files generated by the AdvanceMAME emulator.
To compress the files this utility uses the following strategies:

- Remove all ancillary chunks.
- *
- Concatenate all the IDAT chunks.
- *
- Use the 7zip Deflate implementation.
