 SCADFormat is, shall we say, "opinionated" in the way that it formats OpenSCAD code. In other words, there are no configuration options that alter the way code is formatted.

+Compared to hugheaves/scadformat not much has changed. All I did was increase the indent size from 2 to 4, since that's also my personal preference as well as the VSCode extension I use has a hard time with 2 indents. Other than that, I also removed the creation of the backup file (files suffixed with a date and `.scadbak`), as my directory got cluttered with old backups quite quickly, even though I had no use for those files.
