 %description
 This is an implementation of EdDSA in Java. Structurally, it
 is based on the ref10 implementation in SUPERCOP (see
 http://ed25519.cr.yp.to/software.html).
+
 There are two internal implementations:
+
 * A port of the radix-2^51 operations in ref10
   - fast and constant-time, but only useful for Ed25519.
 * A generic version using BigIntegers for calculation
