Fix subcommand selection..

..by sorting the list of subcommand function names in descending order
of how many '_' are in them. This means that `abra app <app> version`
will always be matched before `abra version`.

+`abra` is a command-line tool for managing your own [Co-op Cloud](https://cloud.autonomic.zone). It can provision new servers, create applications, deploy them, run backup and restore operations and a whole lot of other things. It is the go-to tool for day-to-day operations when managing a Co-op Cloud instance.
 
-Specific releases are available via the project [release page](https://git.autonomic.zone/autonomic-cooperative/abra/releases).
-
-## Changes
+## Change log
 
 See [CHANGELOG.md](./CHANGELOG.md).
 
-## Hacking
+## Documentation
+
+> [docs.cloud.autonomic.zone](https://docs.cloud.autonomic.zone/)
+
+## Install
+
+Install the latest stable release:
 
 ```sh
-git clone ssh://git@git.autonomic.zone:2222/autonomic-cooperative/abra.git
-cd abra
-make dev_install
+curl https://install.abra.autonomic.zone | bash
 ```
 
-See [autonomic-cooperative/installer-scripts](https://git.autonomic.zone/autonomic-cooperative/installer-scripts) for the installer script deployment. To make a release, just add an entry to [CHANGELOG.md](./CHANGELOG.md) and the [installer](./installer) (following [semver](https://semver.org/) please) and then `git tag x.x.x && git push origin main --tags`. If you want the [installer-scripts](https://git.autonomic.zone/autonomic-cooperative/installer-scripts) deployment to pick that up, you'll need to change the version number in the [Makefile](https://git.autonomic.zone/autonomic-cooperative/installer-scripts/src/branch/main/Makefile) and run `make` in that repository and push the changes.
+or the bleeding-edge development version:
 
-## Specify what to deploy where
+```sh
+curl https://install.abra.autonomic.zone | bash -s -- --dev
+```
 
-You can use `abra` in one of 2 ways:
+The source for this script is [here](./installer/installer).
 
-1. Clone a `compose-stack`, create an `.envrc` in it, and run `abra` in that
-   directory. Be sure to set `ABRA_STACK_DIR=.`
-2. "Monorepo mode": keep all your `compose-stack`s in one directory and all your `env` files in
-   another, e.g.:
-   ```
-	 $ tree
-   .
-   ├── apps
-   │   ├── mediawiki.demo.autonomic.zone.env
-   │   ├── wordpress.demo.autonomic.zone.env

-       ├── swarmpit
-       ├── traefik
-       └── wordpress
-		$ abra -e apps/mediawiki.demo.autonomic.zone.env deploy
-    ```
+## Update
 
-## Examples
+Run `abra upgrade` to automatically download and install the latest release
+version.
 
-- `abra run mariadb mysqldump gitea -p'GdIbMeS09SURRktBnm3jcTufsL5z0MPd' | gzip > ../git.autonomic.zone_mariadb_`date +%F`.sql.gz`
+To update the development version, run `abra upgrade --dev`.
+
+## Hack
+
+It's written in Bash version 4 or greater!
+
+Install it via `curl https://install.abra.autonomic.zone | bash -s -- --dev`, then you can hack on the source in `~/.abra/src`.
+
+The command-line interface is generated via [docopt](http://docopt.org/). If you add arguments then you need to run `make docopt` ro regenerate the parser.
+
+Please remember to update the [CHANGELOG](./CHANGELOG.md) when you make a change.
+
+## Release
+
+- Change the `x.x.x` header in [CHANGELOG.md](./CHANGELOG.md) to reflect new version and mark date
+- Update versions in [installer/installer](./installer/installer) and [abra](./abra)
+- `git commit` the above changes and then tag it with `git tag <your-new-version>`
+- Then `git push` and `git push --tags`
+- Deploy a new installer script `make release-installer`
+- Tell the world
