The define-module name must match the file path; this is a requirement in the standard-reports folder. Can't remember where exactly this is enforced.

The 'pnl is used to direct the multicol-report-options-generator to provide options suitable for profit-n-loss aka 'pnl. See the definition of multicol-report-options-generator and locate where 'pnl is tested. > uuidgen on my Mac issues 36-character uuids, with hyphens and uppercase, > like this: > 47170C69-F87E-4A3B-9A97-8B97F56F5DFD > Would I need to edit them to give 32-character lowercase uuids, lacking > hyphens? > Actually any unique string of any length will do. > Obviously, I have to take responsibility for my own programming > experiments (and errors), but I’d appreciate a quick steer from someone > with Scheme experience.
