This package can process uploads and store them with unique names.

It provides a PHP script to process an uploaded file by checking if it has one of the supported file name extensions.

The script also checks if the file has the name of a file that has not yet been uploaded.

If the file passes all the checks, the script moves the file to a separate directory using a hash of the original file name to create a new file named for the stored file.
