77 
78    Not Collective
79 
80    Input Parameters:
81 +  name_solver - name of a new user-defined solver
82 .  path - path (either absolute or relative) the library containing this solver
83 .  name_create - name of routine to create method context
84 -  routine_create - routine to create method context
85 
86    Level: developer
87 
88    Notes:
89    PetscViewerRegisterDynamic() may be called multiple times to add several user-defined solvers.
90 
91    If dynamic libraries are used, then the fourth input argument (routine_create)
92    is ignored.
93 
94    Sample usage:
95 .vb
96    PetscViewerRegisterDynamic("my_viewer_type",/home/username/my_lib/lib/libO/solaris/mylib.a,
97                "MyViewerCreate",MyViewerCreate);
98 .ve
99 
100    Then, your solver can be chosen with the procedural interface via
101 $     PetscViewerSetType(ksp,"my_viewer_type")
102    or at runtime via the option
103 $     -viewer_type my_viewer_type
