hledger can optionally produce debug output (if enabled with `--debug=N`); hledger can produce debug output (if enabled with `--debug[=N]`).
this goes to stderr, and is not affected by `-o/--output-file`. N ranges from 1 (least output, the default) to 9 (maximum output).
If you need to capture it, use shell redirects, eg: `hledger bal --debug=3 >file 2>&1`. Debug output goes to stderr, and is not affected by `-o/--output-file`.
It will appear interleaved with normal output, which can help in understanding when code is evaluated.
To capture it in a log file instead, use shell redirects, eg: `hledger bal --debug=3 2>hledger.log`.
