For now we have a couple of hardcoded strings of matches for 'Boolean to decimal' preprocessing step:

"true,t,yes,y,on,up,running,enabled,available,ok,master"
"false,f,no,n,off,down,unused,disabled,unavailable,err,slave"

It would be great to have ability to cusomize them without recompilling server and proxy binaries. E.g., I'd like to add 'passed/failed' and have only one way - edit sources and build my own binaries.
