134 
135    Not collective
136 
137    Input Parameters:
138 +  name_solver - name of a new user-defined solver
139 .  path - path (either absolute or relative) the library containing this solver
140 .  name_create - name of routine to create method context
141 -  routine_create - routine to create method context
142 
143    Notes:
144    PCRegisterDynamic() may be called multiple times to add several user-defined preconditioners.
145 
146    If dynamic libraries are used, then the fourth input argument (routine_create)
147    is ignored.
148 
149    Sample usage:
150 .vb
151    PCRegisterDynamic("my_solver","/home/username/my_lib/lib/libO/solaris/mylib",
152               "MySolverCreate",MySolverCreate);
153 .ve
154 
155    Then, your solver can be chosen with the procedural interface via
156 $     PCSetType(pc,"my_solver")
157    or at runtime via the option
158 $     -pc_type my_solver
