I think this presents a problem if one is intending to use g_wham to calculate 
PMF from the umbrella sampling protocol.  When using direction for 
pull_geometry, g_wham fails with a fatal error:

-------------------------------------------------------
Program g_wham, VERSION 4.0.5
Source code file: gmx_wham.c, line: 1337

Fatal error:
Pull geometry direction not supported
