## Usage

```js
var WIM = require( 'wim' )
```

### Read a WIM header

```js
var image = new WIM.Image()

image.open( 'sources.wim', function( error ) {
  if( error ) return handleError( error )
  image.readHeader( function( error, header ) {
    console.log( header )
  })
})
```

```js
Header {
  imageTag: 'MSWIM\u0000\u0000\u0000',
  size: 208,
  version: 68864,
  flags: 262274,
  compressedSize: 32768,
  guid: <Buffer 29 f7 36 06 03 77 e4 41 96 f8 1b b8 69 fd 49 7d>,
  partNumber: 1,
  partCount: 1,
  imageCount: 2,
  offsetTable: FileHeader {
     size: 461850,
     flags: 2,
     offset: 307668199,
     originalSize: 461850
  },
  xmlData: FileHeader {
    size: 3824,
    flags: 2,
    offset: 308130049,
    originalSize: 3824
  },
  bootMetadata: FileHeader {
     size: 920042,
     flags: 6,
     offset: 306748157,
     originalSize: 4555704
  },
  bootIndex: 2,
  integrity: FileHeader {
    size: 0,
    flags: 0,
    offset: 0,
    originalSize: 0
  },
  reserved: <Buffer 00 00 00 00 00 00 00 00 00 00 00 00 00  ... >
}
```

### CLI Usage
```
npx wim wimfile -h|-x|-m
  dump wimfile header, xml data or metadata
```

### CLI - read version from windows installation ISO 

ISO mount on filesystem is Linux-specific here.

```
mount win10.iso /mnt/win10/ -o loop
npx --package @fredericgermain/wim wim /mnt/win10/sources/install.wim -x | npx --package @toycode/xml2json-cli xml2json | jq -r .WIM.IMAGE[0].WINDOWS[0].SERVICINGDATA[0].PKEYCONFIGVERSION[0]
```

You get `10.0.19041.1202;2016-01-01T00:00:00Z` for instance.
