        multi-platform file synchronization tool

        Project homepage: https://github.com/bcpierce00/unison

        Description

        Unison is a file-synchronization tool for Unix and Windows. It allows two replicas of a collection of files and directories to be stored on different hosts (or different disks on the same host), modified separately, and then brought up to date by propagating the changes in each replica to the other. This packages contains the command-line tool and the manpage.

        | Running unison on OpenBSD
        +-----------------------------------------------------------------------
        
        This version of unison is compatible with:
        - unison 2.52 or newer. You do not have to pay any attention to OCaml
          compiler versions.
        - unison 2.51 if both versions are compiled with same OCaml compiler
          version.
        - unison 2.48 if both versions are compiled with same OCaml compiler
          version.
        
        It is possible to use the OPAM OCaml package manager to build unison
        with the same version of the OCaml compiler on all machines:
        
        doas pkg_add opam
        export OPAMROOT=~/opam_unison
        opam init --no-setup --compiler ocaml-base-compiler.%VERSION%
        opam install unison lablgtk  # To build without the gui, remove lablgtk
        $(opam var bin)/unison
        
        Where %VERSION% is the OCaml version that is used on all machines.
        
        Common issue
        =============
        Unison sometimes reports chown() failures that are actually failures to
        change group ownership. This can occur when a user does not belong to
        the specified group and is the owner of the file, or is not the
        superuser. Issue can be addressed by setting the option 'group' to
        'false'.
