fortran routine for v8

[daniele]

Hello,
I wrote a large code inside cs_user_boundary_conditions_ale.f90 to impose some desired mesh displacement, in the version 7 of CS.
I would like to move to v8, but the cs_user_boundary_conditions_ale.f90 does not exist anymore. Is there a workaround to make it work on v8, to avoid writing one in C from zero?
Thank you very much in advance for your help.
Best regards,
Daniele
