1. Brute-force: This method does not consider any interactions between keywords and input blocks, and instead combines documentation randomly. Specifically, it randomly combine keywords, options, and settings to produce valid input files. To facilitate this, we scraped all options and keywords from version 5.0.4 of the ORCA manual. Additionally, we extracted all input blocks from the manual, capturing both the setting option and setting value as full lines, and documented which setting lines belonged to which option block.
