$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."
