[petsc-dev] Recover SNES ex6.c?

[Karl Rupp]

Hi,

as I just noticed, src/snes/examples/tutorials/ex6.c was kicked out two 
days ago: http://petsc.cs.iit.edu/petsc/petsc-dev/rev/cb006da503e9

However, ex6.c is included in the user manual, now causing the 
compilation to fail. With ex6.c containing matrix-free Jacobians, which 
are not included in ex2.c, the respective section in the manual would 
require considerable rewriting. Conversely, merging the matrix-free 
stuff from ex6.c to ex2.c is not an option either, as ex2.c is used 
elsewhere in the manual, leading to a fairly non-intuitive 
documentation. Any ideas aside from recovering ex6.c?

Best regards,
Karli
