+$Usage
+For each filename given, $name uuencodes the file, using the final
+component of the file's path as the stored filename in the uuencoded
+archive and, with a .${SUF} appended, as the name to store the archive in.
+Example: 
+$name /tmp/foo
+The file /tmp/foo is uuencoded, with \"foo\" stored as the name to uudecode
+the file into, and the output is stored in a file in the current directory
+with the name \"foo.${SUF}\".
+Options:
+-f: Normally, if the file the output would be stored in already exists,
+    it is not overwritten and an error message is printed.  If -f (force)
+    is given, it is silently overwritten.
+-h: Print this help."
