Dear developer we are performing an empirical study at 
Polytechnique
Montreal on software anti-patterns and refactoring and we
need your inputs . 
We contact you because of your experience on 
Java developement.
 
The study consists of 20 refactoring patches proposed by developers and
an automated software tool. The patches are divided into 4
groups.
The task consists of identifying if the refactoring patches
 were generated by a 
developer
or by 
software
tool, and to 
vote
them according to their quality.
Your participation will allow us to collect data to understand the
perspective of developers about refactoring and to improve automated
approaches.
This survey is 
anonymous
and the collected data will be kept 
confidential
