+Package: gathertweet
+Title: Gather Tweets from the Command Line with rtweet
+Version: 0.0.0.9000

+Description: A command line utility for common tweet gathering
+    tasks. Leverages the rtweet package for cron-friendly,
+    boilerplate-free tweet collection. Currently in progress and only
+    suitable for small search-based tweet collection projects.
