 DESCRIPTION
   Upload data and fetch URL from the pastebin http://sprunge.us
- 
+
 USAGE
   $0 filename.txt
   $0 text string
   $0 < filename.txt
   piped_data | $0
- 
+
 NOTES
 --------------------------------------------------------------------------
 * INPUT METHODS *
 $0 can accept piped data, STDIN redirection [<filename.txt], text strings following the command as arguments, or filenames as arguments.  Only one of these methods can be used at a time, so please see the note on precedence.  Also, note that using a pipe or STDIN redirection will treat tabs as spaces, or disregard them entirely (if they appear at the beginning of a line).  So I suggest using a filename as an argument if tabs are important either to the function or readability of the code.
- 
+
 * PRECEDENCE *
 STDIN redirection has precedence, then piped input, then a filename as an argument, and finally text strings as an arguments.
- 
+
   EXAMPLE:
   echo piped | "$0" arguments.txt < stdin_redirection.txt
- 
+
 In this example, the contents of file_as_stdin_redirection.txt would be uploaded. Both the piped_text and the file_as_argument.txt are ignored. If there is piped input and arguments, the arguments will be ignored, and the piped input uploaded.
- 
+
 * FILENAMES *
 If a filename is misspelled or doesn't have the necessary path description, it will NOT generate an error, but will instead treat it as a text string and upload it.
