stacktrace-metadata
Modify given `err` object to be more useful - adds `at`, `line`, `column`, `place` and `filename` properties and also cleans stack traces.
approximate-number
Converts numbers into a more human-friendly format, similar to `ls`'s `--human-readable` flag (`ls -lh`) or Stack Overflow's reputation numbers. For example, 123456 becomes '123k'.
