-Description: What the package does (one paragraph).
+Description: Provides a fast, lightweight, and vectorized base 64 engine
+    to encode and decode character and raw vectors as well as files stored
+    on disk.  Common base 64 alphabets are supported out of the box
+    including the standard, URL-safe, bcrypt, crypt, 'BinHex', and
+    IMAP-modified UTF-7 alphabets. Custom engines can be created to
+    support unique base 64 encoding and decoding needs.
