Provides a text extraction API for file content, that can hook into different extractor
engines based on availability and the parsed file format. The output returned is always a string of the file content.

Via the `FileTextExtractable` extension, this logic can be used to
cache the extracted content on a `DataObject` subclass (usually `File`).

The module supports text extraction on the following file formats:

 * HTML (built-in)
 * PDF (with XPDF or Solr)
 * Microsoft Word, Excel, Powerpoint (Solr)
 * OpenOffice (Solr)
 * CSV (Solr)
 * RTF (Solr)
 * EPub (Solr)
 * Many others (Tika)

## Requirements

 * SilverStripe ^3.1
 * (optional) [XPDF](http://www.foolabs.com/xpdf/) (`pdftotext` utility)
 * (optional) [Apache Solr with ExtracingRequestHandler](http://wiki.apache.org/solr/ExtractingRequestHandler)
 * (optional) [Apache Tika](http://tika.apache.org/)

## Installation

```js
composer require silverstripe/textextraction
```

The module depends on the [Guzzle HTTP Library](http://guzzlephp.org),
which is automatically checked out by composer. Alternatively, install Guzzle
through PEAR and ensure its in your `include_path`.
