 # Maven toolbox scripts
 
-This folder contains a small set of scripts to automate dependency updates across multiple Maven projects in a workspace.
+This folder contains helpers for inspecting Maven project dependencies and formatting Java code.
 
 ## Prerequisites
 
 - Debian/Linux with `bash`
 - `python3` (for `build-dependency-tree.py`)
-- `git`
-- `mvn` (and the Maven Versions Plugin available, since `versions:*` goals are used)
+- `mvn`
 - Workspace layout: a directory containing multiple Maven projects with `pom.xml` files
 
 All scripts are intended to be run from this folder (they `cd` to the script directory).

 ```bash

-
----
-
-## `prepare-release`
-
-Prepares and pushes a git branch for a maven project directory for either:
-
-- `--mode=release`: update dependencies to latest releases (default mode)
-- `--mode=major`: bump the project version to `X.0-SNAPSHOT` and update dependencies to latest snapshots
-
-It expects a clean `pom.xml`.
-
-### Usage
-
-```bash
-<toolbox>/mvn/prepare-release.sh [--mode=release] --branch=<branch-name> [project-dir]
-<toolbox>/mvn/prepare-release.sh --mode=major --version=<major> --branch=<branch-name> [project-dir]
-```
-
-### Examples
-
-Update the current directory project to the latest releases:
-
-```bash
-<toolbox>/mvn/prepare-release.sh --branch=RELEASE
-```
-
-Prepare major version 7.0-SNAPSHOT for a single project:
-
-```bash
-<toolbox>/mvn/prepare-release.sh --mode=major --version=7 --branch=major-7 ~/workspace/some-project
-```
-
----
-
-## `major-upgrade`
-
-Runs a major upgrade across *multiple* Maven projects in a workspace, in dependency order.
-
-It uses `build-dependency-tree` to generate an ordered list of project directories, then runs `prepare-release --mode=major` for each directory. Progress is checkpointed so the run can be resumed.
-
-### Usage
-
-```bash
-<toolbox>/mvn/major-upgrade.sh <major> [workspace_dir]
-```
-
-- `<major>`: required major version number (e.g. `7`)
-- `workspace_dir`: optional, defaults to `$HOME/workspace`
-
-### Files created
-
-For major version `$v` in workspace `$WS`:
-
-- `$WS/major-$v.tree` — dependency-ordered list of projects (generated once, reused on reruns)
-- `$WS/major-$v.done.tree` — checkpoint file of already-processed directories
-- `$WS/major-$v.log` — combined stdout/stderr log of all `prepare-release` runs
-
-### Example flow
-
-1. Go to your workspace directory and make sure all repos are cloned. Ensure all repos are
-on a clean git state (on `dev` branch).
-    ```bash
-    cd $WS
-    <toolbox>/git/pull-and-clean.sh
-    ```
-2. Generate a dependency `major-$v.tree` and vet it manually. Entries can be removed if needed.
-    ```bash
-    <toolbox>/mvn/build-dependency-tree.py > major-$v.tree
-    edit major-$v.tree
-    ```
-3. Run the routine to process all pom's in order. If one fails, fix the repo and rerun the same command to resume. Already completed directories are skipped based on `major-$v.done.tree`.
-    ```bash
-    <toolbox>/mvn/major-upgrade.sh $v
-    ```
