Allows a fast way to create a large amount of categories with whatever slugs you'd like and nested categories as well!
This section describes how to install the plugin and get it working.

/wp-content/plugins/
named batch-category-import
- Upload all files into
/wp-content/plugins/batch-category-import/
directory
- Login Wordpress administration panel.
- Activate the plugin through the 'Plugins' menu.
- Go to Posts -> Category Import and start importing!
v1.0.1 - Added support for comments by making a third dollar-sign '$' in the category string.
