Grunt task around [preprocess](https://github.com/jsoverson/preprocess) npm module
## What does it look like?
```html
Your App
Debugging mode -
```
```js
var configValue = '/* @echo FOO */' || 'default value';
// @ifdef DEBUG
someDebuggingCall()
// @endif
```
See preprocess documentation for more information
## Getting Started
Install this grunt plugin next to your project's Gruntfile with: `npm install --save-dev grunt-preprocess`
Then add this line to your project's Gruntfile:
```javascript
grunt.loadNpmTasks('grunt-preprocess');
```
## Options
#### context
Type: `Object`
Default: `{NODE_ENV: 'development'}`
The additional context on top of ENV that should be passed to templates. If NODE_ENV is not set, the task sets it to `development` by default.
#### inline
Type: `Boolean`
Default: `undefined`
Required to enable overwriting of source files
#### srcDir
Type: `String`
Default: ``
The directory where to look for files included via `@include` variants and `@extend`.
#### srcEol
Type: `String`
Default: EOL of source file or `os.EOL` if source file contains multiple different or no EOLs.
The end of line (EOL) character to use for the preprocessed result. May be one of:
- `\r\n` - Windows
- `\n` - Linux/OSX/Unix
- `\r` - legacy Mac
#### type
Type: `String`
Default: file extension of the file to be processed
The syntax type of source file to preprocess. See [preprocess() description](https://github.com/jsoverson/preprocess#optionstype) for a list of all supported file types.
## Example Usage
```js
preprocess : {
options: {
context : {

dest : 'test/test.processed.js'
},
multifile : {
files : {
'test/test.processed.html' : 'test/test.html',
'test/test.processed.js' : 'test/test.js'
}
},
inline : {
