<><> Unix support infrastructure ><><><><><><><><><><><><><><><><><><><><><><><>


opam and the OCaml ecosystem in general require various Unix tools in order to operate correctly. At present, this requires the installation of Cygwin to provide these tools.


How should opam obtain Unix tools?
> 1. Use tools found in PATH (Cygwin installation at C:\cygwin64)
2. Automatically create an internal Cygwin installation that will be managed by opam (recommended)
3. Use Cygwin installation found in C:\cygwin64
4. Use another existing Cygwin/MSYS2 installation
5. Abort initialisation


[1/2/3/4/5] 1
Checking for available remotes: rsync and local, git.
- you won't be able to use mercurial repositories unless you install the hg command on your system.
- you won't be able to use darcs repositories unless you install the darcs command on your system.

Everything as up-to-date as possible
However, you may "opam upgrade" these packages explicitly at these versions (e.g. "opam upgrade ocaml.5.5.0"), which will ask permission to downgrade or uninstall the conflicting packages.
Nothing to do.
