- * NOTE: this is part of libzzipmmapped (i.e. it is not libzzip).
- * ==================
- *
- * The mem_disk cache will parse the central information of a zip archive
- * and store it internally. One the one hand it allows to find files
- * faster - no disk access is required and endian conversion is not
- * needed. If zzip is compiled with zip extensions then it is about
- * the only way to build maintainable code around the zip format.
- *
- * Note that 64bit support is almost entirely living in extension
- * blocks as well as different character encodings and file access
- * control bits that are mostly platform specific.
