 This library provides common methods used in gp* command. 

==METHOD LIST

  * help                           : print help message

  * NumRu::Netcdf.copy_global_att  : Copy global attributes from a Gphys 
                                     variable. It operates only when a gphys 
                                     variable consist of a NetCDF file.

==HISTORY

  2005/08/23  S Takehiro (created)
  2008/02/14  S Takehiro (copy_global_att can deal with GPhys 
                          which consists of multiple files)
  2015/09/06  H Kashimura && S Takehiro (fixed for installation by gem)
