Automated Reconstruction of LoadRunner Scripts

Overview
The following are early versions of scripts I have used to cleanup and reformat LoadRunner scripts after I have recorded them. Ultimately, my intention was to automate the inclusion of parameters and other code such as standard libraries.
The Scripts
