Location aliases
 
118
================
 
119
 
 
120
Bazaar defines several aliases for locations associated with a branch.  These
 
121
can be used with most commands that expect a location, such as `bzr push`.
 
122
 
 
123
The aliases are::
 
124
 
 
125
%s
 
126
For example, to push to the parent location::
 
127
 
 
128
    bzr push :parent
