I do.  That's why I avoid using that tool.   Look at your example.    
How am I supposed to know in advance to look in the directory tags/ 
v1_8_4/ChangeLog unless I get that information from somewhere else?   
Also, If I need that version I'm going to have to download the whole  
thing rather than just use a cheap local delta.  A better tool would  
give me all the information I need without external source, without  
lots of disk space, and without lots of bandwidth.
