Explore the different tools below by expanding the details.

Extracter ./swfs [options] extract

The extract tool dumps all png and binary files of the swf files in a directory.

Argument	Explanation
input	Path to the directory where the swf files are located
output	Path to the directory you want the extracted files to be placed
[workers]	Size of worker pool. Higher number will increase the concurrent use of swfdump and swfextract. Default is 2.

./swfs -input /swfdir -output /extracted -workers 2 extract

Bundler ./swfs [options] bundle

The bundle tool replaces the extracted folders into individual `.asset` files.

Argument	Explanation
input	Path to the directory where the extracted files are located
[workers]	Size of worker pool. Higher number will increase the concurrency of the program. Default is 5.

./swfs -input ./extracted -workers 5 bundle

The .asset file structure:

## Content of .asset files are structured as key value pairs
## separated by "=n". Multiple assets are separated with 
## double newline "nn". First line is always the format version.

version=
1


some_extracted_image.png=
�PNG...


some_extracted_binary.bin=
<xml>
    ....
</xml>

To parse .asset files, split on nn, then loop through each part. Split each part on =n to get [0]filename and [1]filedata.
