The "robots.txt.dist" file is a default or a template file used in web development for creating a "robots.txt" file.
The "robots.txt" file is a text file that is placed in the root directory of a website and provides instructions to web robots (also known as web crawlers or spiders) on how to interact with the website's content. It can specify which pages should be crawlable and indexable by search engines, and which ones should be excluded.
The ".dist" extension in "robots.txt.dist" indicates that it is a distribution file or a template file, which can be customized or renamed to "robots.txt" as per the specific needs of a website. Web developers can use this template to create the actual "robots.txt" file with the desired instructions for web robots.
