 - Reads ZIP files using Unsafe backed mapped files.
     - Using `FileChannel.map` yields `MappedByteBuffer` which uses `int` values, limiting files up to about 2GB
     - Our `UnsafeMappedFile` implementation uses `long` which far exceeds the GB file size range
+- Highly configurable, offering 3 ZIP reading strategies out of the box _(See `ZipIO` for convenience calls)_
+    - Std / Forward scanning: Scans for `EndOfCentralDirectory` from the front of the file, like many other tools
+    - Naive: Scans only for `LocalFileHeader` values from the front of the file, the fastest implementation, but obviously naive
+    - JVM: Matches the behavior of the JVM's ZIP parser, including a number of odd edge cases. Useful for opening JAR files to mirror `java -jar <path>` behavior.
