Python Wrapper for Googles Robotstxt Parser

Provides python access to Googles parser for robot.txt files as used by their GoogleBot webscraper.

Websites may provide an optional robots.txt file in their domains root to govern the access and behavior of web scrapers. One of the most famous webscrapers GoogleBot is responsible for promoting this standard and sites interested in SEO will closely conform to GoogleBot behavior.

All credit for the parser goes to the Google team who created, open sourced and promoted it.

SEO (Search Engine Optimization): The process of modifying a websites content or metadata to boost rankings in search engines page indexes. Higher rankings lead to higher positions in user searches leading to more visitors. For further details, see the SEO wikipedia page.

"""
