wrapper the binary into library, so can be called by other node code?

[ulion]

currently, this tool can only be called from cmdline.

but I'd like to call it within my node.js code, after create a new index, I call this, then update the alias.

I did plan directly use official _reindex command, but, the aws ES just not support that command. so why this module not wrapper itself then it can be called by other node script?
