| ######################################### | |
| # Article Extraction Library | |
| # This library is used to handle scraping and extraction of articles from web pages. | |
| # Currently, uses a combination of beatifulsoup4 and trafilatura to extract article text. | |
| # Firecrawl would be a better option for this, but it is not yet implemented. | |

| # Function List | |
| # | |
| # 1. get_page_title(url) | |
| # 2. get_article_text(url) | |
| # 3. get_article_title(article_url_arg) | |
