Handle Morloc installation and removal

Setup morloc containers, scripts, and home for either the latest version of Morloc or for the specified version.

The only dependency is a container engine, currently two docker and podman are supported.

You can retrieve the manager with curl:

curl -o morloc-manager https://raw.githubusercontent.com/morloc-project/morloc-manager/refs/heads/main/morloc-manager.sh

Then move it into your path (e.g., move it to ~/.local/bin) and make it executable.

Basic usage information is available for the main script and all subcommands:

morloc-manager -h
morloc-manager install -h
morloc-manager uninstall -h

To install the latest version of Morloc, run install with no arguments:

morloc-manager install

This will retrieve required containers, create the morloc home directory, and make four executable scripts:

1. menv: runs commands in a Morloc container. Examples:

$ menv morloc make -o foo foo.loc
$ menv ./foo double 21

2. morloc-shell: enter the "full" container in a shell

   • contains Python, R, and C++ compiler
   • contains vim and other conveniences

3. menv-dev: runs commands in a dev container

   • contains Haskell tools for building from source
   • can access to all system executables

4. morloc-shell-dev: enter the dev shell
