+basE91 is an advanced method for encoding binary data as ASCII characters.
+It is similar to UUencode or base64, but is more efficient.
+
+The overhead produced by basE91 depends on the input data. It amounts at most
+to 23% (versus 33% for base64) and can range down to 14%, which typically
+occurs on 0-byte blocks.
+
+This makes basE91 very useful for transferring larger files over binary unsafe
+connections like e-mail or terminal lines.
