Usage Instructions

Download the script and ensure it has correct permissions to be executed by the appropriate user. Modify the URL value in the script to point at your WP install.

Then run: ./build.sh my-static-folder

This will create a directory named "my-static-folder" which you can verify and deploy. I've found that wget can sometimes mangle certain special characters, escaping them as HTML entities. You can implement some perl regex on Line 19 of the script to resolve any issues like this.
