About:
Bookloupe is a command-line utility designed to analyze Project Gutenberg e-book files for common formatting and typographical errors. It scans for issues such as incorrect spacing, punctuation errors, and structural inconsistencies that violate PG standards. This tool helps producers and proofreaders ensure high-quality, clean text files for the Gutenberg archive.

Key Features:

Detects common formatting and typographical errors
Validates text against Project Gutenberg standards
Outputs detailed error reports for easy review
Command-line interface suitable for automation

Use Cases:

Quality assurance for new Project Gutenberg submissions
Automated checking of e-book files in a proofreading workflow
Cleaning up legacy text files to meet modern standards

Alternatives:

gutcheck – An older, unmaintained PG checker; bookloupe is a more modern and actively maintained alternative.
Custom Regex Scripts – Ad-hoc scripts offer less comprehensive coverage and lack the standardized rule set of bookloupe.
