+
+Scotty is the most simple network file transfer utility. It provides
+no security what so ever.
+
+To expose a file/folder for anyone to catch:
+* scotty up [folder/file name]
+* Pick the hostname from the printed list, and send it to the receiver.
+
+To download the exposed folder/file:
+* scotty down [sender host name]
+* Download happens to the current working directory. 
+* By default, any existing file is overwritten.
+
+Add tar options by modifying a variable:
+* SCOTTY_TAR="pass your tar options here" scotty ...
+
+Scotty uses port '$PORT' to transfer files. Downloading host needs
+to see the uploader directly.
