 == Summary of main features ==
 
- * The following algorithms will be included in the first implementation:
-   * Clamped and Flow Relaxation Scheme. (Clamped is FRS with rimwidth=1).
+ * The following algorithms will be definitely be included in the first implementation:
+   * Clamped and Flow Relaxation Scheme for all variables. (Clamped is FRS with rimwidth=1).
+   * Zero gradient condition for all variables. 
    * Flather radiation condition on barotropic solution.
-   * NPO version of Orlanski radiation condition as currently included in OBC.
-     Plan to code ''implicit'' time-stepping for greater stability and to avoid
-     OBC restarts. May also code normal, and fully 2D Orlanski condition.
-   * "Mercator-style" barotropic boundary conditions.
    * Tidal harmonic forcing (included in Flather boundary condition).
+   * Orlanski radiation condition with normal projection of oblique radiative velocities (NPO)
+     for T and S, 3D and 2D velocities. Plan to code ''implicit'' time-stepping for greater stability and to avoid
+     OBC restarts (''Marchesiello et al 2001''). 
+   * sponge layer (enhanced viscosity near the boundary)
+
+ * The following algorithms may be included:
+   * Orlanski radiation condition with normal velocities and fully 2D velocities.
+   * Other conditions on barotropic solution from ''Chapman 1985''
 
  * There will be two ways of specifying the boundary geometry:
