######################################### | |
# 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) | |
