Automate scraping and aggregation

- A program that visits specified websites, reads their pages, processes instructions written in scripts, extracts specific data from those pages [name, location, dates, etc.], then saves that data in another more structured format to incorporation into website or app. - Program will scan websites for changes in data by comparing previous values stored to what's currently on the page. - Automated update process (eg, catalog updates every N hours automatically) - no manual intervention required. - Customer service tool enabling non-programmers to add or remove websites from the list of sites to visit. - If data is hidden behind registration walls, the program will also need to enter credentials to access and then scrape the data.
