I am in the process of preparing for the project is to create a unified catalog for several libraries through the  Vufind system
My question
Does the Vufind  system support all versions of a Koha system or Evergreen system supports certain versions? What?
The second question
 is I know that the system does not support Arabic language as a front? But supports recordings in Arabic? How can Syndication and interfaces?

Please help me
Thank you very much
