what is the exactly version of Ragel this module is using?

[aCayF]

currently, i wanna add the use cmd to the module as it is not supported yet, and i have noticed that this module uses Ragel to generate response parsers (in C), so any modification on the ngx_http_beanstalkd_response.rl file will be reflected on the final ngx_http_beanstalkd_response.c file compiled to by Ragel tool, the differences between two commits will stay as less as possible if contributors use exactly the same Ragel tool.

I forgot the exactly version. If you code can pass the all the tests, it doesn't matter which version you use.
