Usage in the README

[ELLIOTTCABLE]

There's no indication in the README of how to use this from the command-line. I'm a Ruby, JavaScript, and C programmer; I have no experience with Java, and I have no idea how to run the commands described in the README using a .jar file.

A basic “how to download, and example commands I can run at the shell's command-line” section in the REAMDE would be welcome.

Download by clicking the binary download links in the readme (assuming as you're not a Java coder you won't want to compile from source). Jar files are run from command line with "java -jar [jarfile].jar" (your Java install must be on your PATH, otherwise either add it or use the full path e.g. "'C:\Program Files\Java\jre7\bin\java' -jar [jarfile].jar'), just put the arguments after that like you would with any other command-line program.

For example, if you had the 1.1 binary ("cli-nbt-1.1.jar") and an uncompressed NBT file (nbt.nbt) you wanted to edit:
$ java -jar cli-nbt-1.1.jar nbt.nbt
If nbt.nbt is GZIP compressed:
$ java -jar cli-nbt-1.1.jar -g nbt.nbt

Sorry for the late reply, I've been away for the last 2 weeks with no Internet.
