These perl scripts are used to access the ADS database in an easy way, directly from the shell prompt. They are useful to build a bibtex database, retrieve pdf files of a list of paper, or to make simple statistics. There is two sets of scripts : the first one, somehow older, is based on LWP::UserAgent to access directly ADS web pages. The second is a rewrite of the latter using the Astro::ADS library.
You can find they on gitlab or as a tar.
