[ANNOUNCEMENT] New packages: unison2.13, unison2.17; updates to other unison packages


The unison2.13 and unison2.17 packages are now available in the Cygwin
distribution.  In addition, some minor documentation updates have been
made to the unison2.9.1, unison2.9.20, unison2.10.2, unison2.12.0
packages.

Unison is a file synchronizer 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.

The Cygwin packages listed above provide all of the recent stable and
beta releases of Unison.  The versions are separated into different
packages because different versions of Unison will not talk to each
other.  For example, if you are running Unison version 2.10.2 and
attempt to synchronize with a server running version 2.9.20, Unison will
issue an error message about incompatible versions and quit.  (This
restriction has been partially relaxed in versions 2.13 and later:  two
different versions are compatible if the first two numbers in their
version string are the same.  E.g. all versions 2.13.* are mutually
compatible.)  By installing one or more of the packages listed above,
you can run whichever version you need in order to synchronize with your
server.

You can safely install more than one of the unison* packages:  their
executables are named e.g. /usr/bin/unison-2.9.1.exe, so they don't
conflict.  In addition, the package installer will create a symlink from
/usr/bin/unison.exe to /etc/alternatives/unison.exe, and from
/etc/alternatives/unison.exe to one of the installed
/usr/bin/unison-*.exe files.  You can reset this last symlink, either
manually or using update-alternatives(8), to point to whichever version
you want to use by default.

If you are using your Cygwin host as the Unison server, you can invoke
Unison on the client with '-servercmd /usr/bin/unison-$VERSION' to run
the version you want on the server, or put 'servercmd
/usr/bin/unison-$VERSION' into the client's preference file.

Please note that all of the current Unison packages in Cygwin provide
the CLI or text-mode version of Unison.  The GUI (GTK2) version will be
packaged for Cygwin iff I can get it to work.
