 # history
+v0.6.0 (9-Aug-2015):  
+1) add mainfiles option, which allows specification of the main file for packages without a bower.json  
+2) enhancement: alias configs under options or 'require'/'external', can be also `{ name: alias, ... }`, except `['name:alias', ...]`  
+
 v0.5.0 (24-July-2015):  
 1) allow alias to be configured from an sibling node of 'require'/'external', too  
 2) enhancement: if an item existed in both 'require' and 'external' lists, let's remove it from 'require' list
