Usage: $(basename "$0") -p <usenet provider> -i <input dir to upload>
Escape special characters in names if necessary, e.g. brackets: \[testdirectory\]
Use double quotes if the directory has spaces, e.g. \"This is a test directory\"
  -h                 - This help.
  
  Mandatory parameters:
  -p <provider>      - Usenet provider name, e.g. blocknews, eweka, newshosting.
