ForgeToolkit v1.1

This release has feature parity with our closed-source internal tool.

• Moved to PicoCLI for command-line parsing/handling
• Added commands: clean, finalise, flatten, sort, update, validate
• Rewrote documentation

For command help, simply run the JAR on its own without any arguments. For help on a specific command, you can supply that command with no further arguments.

ForgeToolkit v1.0

Initial release.

• When given the path to the primary JSON lang file (en_US.json) and the root directory
  of the Java project, a list of translation strings present in the JSON file but not
  present as a string literal in the Java project will be printed.
