Location aliases

================

Bazaar defines several aliases for locations associated with a branch.  These
 
122
can be used with most commands that expect a location, such as `bzr push`.
 
123
 
 
124
The aliases are::
 
125
 
 
126
%s
 
127
For example, to push to the parent location::
 
128
 
 
129
    bzr push :parent
