Hi all !

If you used Piston 1.2.0 and tried to import a new vendor branch, you  
likely had a problem. This update fixes the problem. From the  
ChangeLog:

- Import subcommand would fail with a “svn: Explicit target required  
(‘vendor/rails’ interpreted as prop value)” error. This was a minor  
error in the import code. Reported by Daniel N.
- The import subcommand could import another revision than what was  
intended, if HEAD was updated while the import is in progress.

Install using:  
$ gem install piston

= Description

Piston is a utility that eases vendor branch management. This is  
similar to svn:externals, except you have a local copy of the files,  
which you can modify at will. As long as the changes are mergeable,  
you should have no problems.

Enjoy !
