bagTools.verify(bagDir, function (err, valid, results) {
  if (err) throw err
  if (valid) console.log('VALID')
  else console.log('FAIL')
})
```

Results is an array of TAP test objects for each verification step. Run against the [LOC bagit-conformance-suite](https://github.com/LibraryOfCongress/bagit-conformance-suite) with `npm test`.

#### Bag Test Verification Status

* 0.97 - Valid/Invalid Passing, Warnings need some work
* ... earlier version before 0.97 all valid

### Bag Fs

Read and write from bags with an fs-like API via [bagit-fs](https://github.com/joehand/bagit-fs).

```js
var bagFs = require('bagit-tools').fs
var bag = bagFs('/put/bag/here', 'sha256', {'Contact-Name': 'Joe Hand'})

// write files to bag's data folder
fs.createReadStream('readme.md').pipe(bag.createWriteStream('/readme.md'))

// ... LATER after all files are written
bag.finalize(function () {
  console.log('finalized')
})
```
