## FYI: These scripts are now maintained in a proper repository:

## Intro: Simple powershell script to install (or replace) a local website and app pool
## Usage: CreateSite.ps1 [WebsiteName] [AppPoolName] [Port] [Path] ([domain\user] [password])
## Note : These scripts require local admin priviliges!
