#gulp-steel-css-postfix

###Usage

use glob pattern to filter your file path;

the filter could also be Array or String, like: 
```JavaScript
{filter:["pages/*.*"]} 
{filter:"lib/*.*"}
```
In your steel-gulpfile, you can use in this way:
```JavaScript
var gscp = require('gulp-steel-css-postfix');

gscp({ 
    filter:["lib/*.*","pages/*.*"] 
})
```

###Example
    If your file path is "src/css/pages/pageA.css", the filter(sub-path) pattern should be "pages/*.*", like:
```JavaScript
function testCss(){
 	gulp.src(['src/css/**/*.*'])
        .pipe($.steelCssPostfix({ 
             filter:["pages/pointsmall/*.*"] 
        }))
	.pipe(gulp.dest(front_base + '/css/'));
}
```
    in the function testCss, the whole file path is "src/css/pages/pointsmall/*.*"
