Thanks for the PR. I like the idea of supporting different comment syntaxes for different file types, though I'm not sure it's necessary to also support multiple block declarations. You could just add rules for each block you want to strip.

Maybe something like this? It would not be a breaking change:

options: {
      start: 'DEV-START',
      end: 'DEV-END'
      commentStart: '/*', // defaults to '/*'
      commentEnd: '*/' // defaults to '*/'
}

Also, I can't merge this with the url for the repo being changed. I assume you are publishing your fork, so folks can use that while I mull over how to proceed.
