-	FILE:  include/smtp.php
-	PURPOSE:
-		Provide SMTP functionality using pure PHP.
-	PRE-CONDITIONS:
-		The functions here require a SMTP server configured to allow relaying.
-	POST-CONDITIONS:
-		The following global variables are returned:
-		$smtp_errornum - error number, 0 if successful
-		$smtp_error - error message(s)
-		$SMTP_TYPE - Optional
-	COMMENTS:
-		The optional $smtp_message_file can be used for sending extremely large
-		messages.  Storing large messages in a variable will consume whatever
-		amount of memory required, which may be more than is available if dealing
-		with messages with large attachments.  By storing them in a file, it becomes
-		possible to read/send bits at a time, drastically reducing memory useage.
-		
-		This library only provides bare-bones SMTP functionality.  It is up to the
-		parent code to form valid RFC822 (MIME) messages.
