    example

    var level  = require('level-test')({ mem: true })
      , glob   = require('level-glob')
      , concat = require('concat-stream')
     
    // create a database
    var db = level()
     
    // insert some data
    var ops = [
      {type: 'put', key: '/readme.md',      value: 'readme' },
      {type: 'put', key: '/assets/app.js',  value: 'js'     },
      {type: 'put', key: '/assets/app.css', value: 'css'    }
    ]
     
    db.batch(ops, function(){
     
      var opts = { values: true, keys: false }
     
      // aggregates multiple streams
      glob(db, ['assets/*', '/*'], opts)
        .pipe(concat(function(value){
          console.log(value === 'cssjsreadme')
        }))
     
      // but those streams are ordered
      glob(db, ['/*', 'assets/*'], opts)
        .pipe(concat(function(value){
          console.log(value === 'readmecssjs')
        }))
     
      // negation only applies to patterns before it
      glob(db, ['assets/*', '!**.md', '/*'], opts)
        .pipe(concat(function(value){
          console.log(value === 'cssjsreadme')
        }))
     
      // so this negative glob does have an effect
      glob(db, ['assets/*', '/*', '!**.md'], opts)
        .pipe(concat(function(value){
          console.log(value === 'cssjs')
        }))
     
    })
