Astro::ADS - An object orientated interface to NASA's ADS database
This module does nothing, and is here as a placeholder in case of need. The user interface to the goodness wrapped in the ADS package can be found in the Astro::ADS::Query module.
NOTE: The API for the ADS is changing and the current interface will disappear. This will be the final revision of this version of Astro::ADS. The new API (described at https://github.com/adsabs/adsabs-dev-api ) will be implemented as version 2.0 sometime in 2015.

The Astro::ADS module itself has no methods, and is just a placeholder module, see Astro::ADS::Query for the actual interface.

When an Astro::ADS::Query object has set the url to a non-default server, the Astro::ADS::Result::Paper objects it returns use the default URL in the references, citations, alsoread and tableofcontents methods. This is likely not what you want if you are doing a lot of followup queries.
You can re-use the original query with the followup method or use v1.21.0 or above which turns the URL from an object variable to a class variable.
Explain the preference to set the class variable using the ads_mirror() method in Astro::ADS::Query at the top of the script so that followup queries go to the expected place. *NB* Also note that the proxy() method is only affects one query object and the user agent looks at the environment variables HTTP_PROXY and NO_PROXY to the exclusion of almost all else. Once again, set $ENV{HTTP_PROXY} at the top of your script for least confusion.
Followups are new query objects, so there are issues with alsoread and tableofcontents. No one has noticed yet and I don't have time to fix it.
This is a "good" idea, but fiddly to implement. Prompt the user for one of the ADS mirrors during the installation and write it into Astro::ADS::Query to save setting it at the beginning of each script
Return undef instead of die()ing.
To install Astro::ADS, copy and paste the appropriate command in to your terminal.
