Unison, courtesy of Benjamin Pierce 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.

I have Unison installed using FinkCommander (see my blogitem on Intel port of Fink) - as a by-product this also gives you an installation of ocaml. Unison is an "unstable" packackage installed from source, so to install it you first need to install Apples's XCode and X11 SDK (from the Tiger installation disks) to provide the compilers, headers etc neded to build the application. Then in Fink Commander Preferences select "Use unstable packages" (Fink tab). From the menus run Source>SelfUpdate then Source>UpdateAll. Finally, select the unison package then install from source (click the .h icon).

To use unison to synchronise your mac with your DICE files, run unison from the command-line in an X terminal window using the server. The DICE unison installation may not be the latest, so use 'unison-[version]' to run a matching version on the Mac. (eg unison-2.10.2). Current DICE version is 2.12.0 - this is not included in the Fink package.

Shuly Wintner provides a variety of binary versions with native Mac UI. Get the 2.12.0 version, to match the unison server on DICE - it appears to run fine under rosetta.
