+     "This package provides a URL-safe base64 encoder and decoder.  In
+contrast to RFC3548, the 62nd character (@code{+}) is replaced with @code{-},
+the 63rd character (@code{/}) is replaced with @code{_}.  Furthermore, the
+encoder does not fill the string with trailing @code{=}.  The resulting
+encoded strings comply to the regular expression pattern @code{[A-Za-z0-9_-]}
+and thus are safe to use in URLs or for file names.  The package also comes
+with a simple base32 encoder/decoder suited for case insensitive file
+systems.")
