Ugly hack to encapsulate instance_id lookup
Added the ability to assh into a node using a tag name; in dire need of refactoring
Added the ability to assh to a single tag name
Minimize roundtrips to lookup account instances
Stop processing if no instances are available
Optimized lookup by instance_id and handled AWSError for invalid instance_ids
Removed note
Minor refactoring on an instance id lookup
Started refactoring the tag lookup block
Started separating node finder logic
Created the find, find_by_instance_id and find_by_tag class methods
Cleaned up find_by_tag a bit more
More find_by_instance_id cleanup
Finished node selection by substring; borrowed code from Jareds goto project
Added error case for no matching tags
Added a more descriptive help banner for assh
Filter resultset tags by instances; added instance id to the multiple node listing
Added trollop; removed unncessary gems
Filter out duplicate resource ids when connecting with a tag name
Hacked in Trollop option for first-node logic
