21  '''This plugin provides actions to switch to the next or previous buffer 
22  in the buffer list, or to switch to a particular filename. Currently, 
23  the sequence is defined arbitrarily by the BufferList class in Views, 
24  but eventually either this plugin or that class should support some sort 
25  of recency list 
26   
27  This plugin provides the following actions: 
28  NextBuffer 
29          Go to the next buffer in the list. 
30  PreviousBuffer 
31          Go to the previous buffer in the list 
32  GoToBuffer 
33          Prompt for a buffer to go to.'''
