All notable changes to this project will be documented in this file.
## Unreleased - ???
- Add `-i` flag to janet binary to make it easier to run image files from the command line
- Remove `thread/` module.
- Add `(number ...)` pattern to peg for more efficient number parsing using Janet's
scan-number function without immediate string creation.

Source should be a path to the Janet module to compile, and output should be the file path of
resulting image. Output should usually end with the .jimage extension.

When this flag is passed, a script passed to the interpreter will be treated as a janet image file
rather than a janet source file.
