Content of this folder follows zlib C sources as close as possible.
That's intended to simplify maintainability and guarantee equal API
and result.
Key differences:
- Everything is in JavaScript.
- No platform-dependent blocks.
- Some things like crc32 rewritten to keep size small and make JIT
work better.
- Some code is different due missed features in JS (macros, pointers,
structures, header files)
- Specific API methods are not implemented (see notes in root readme)
This port is based on zlib 1.2.8.
This port is under zlib license (see below) with contribution and addition of javascript
port under expat license (see LICENSE at root of project)
