## Checkout
This repository accesses the required `manual` repository as a git submodule.
Therefore, make sure to check out this repository and included submodules:

```
git clone --recurse-submodules <git remote repository>
```

If you cloned this repository initially without submobules,
you can always update the content of submodules with the git
`submodule update` command.
Execute the command from the main project directory:

```
git submodule update --init --recursive
```

The ```--init``` flag initializes the submodules before the update.
The ```--recursive``` option searches for nested submodules and ensures they are updated too.

If new commits are available for submodules,
you can always update the **remote** content of submudlues with the git
`submodule update` command.
Execute the command from the main project directory:

```
git submodule update --remote --merge
```

## Python Dependencies
In order to generate the documentation,
first create a Python 3 virtual environment using the
`venv` module included in Python 3:

1. Create a virtual Python environment in the directory `venv`: ```python3 -m venv venv```
1. Activate the virtual Python environment: ```source venv/bin/activate```
1. Install the packages listed in [requirements.txt](./requirements.txt) using `pip`: ```pip install -r requirements.txt```

## Other Dependencies

The LaTex builder is used for PDF output.
`Latex` and `pdflatex` need to be installed.
On a clean (no LaTex compilation yet) operating system like GNU/Debian,
the following dependencies are required to make Latex compile the sources.

```
sudo apt install texlive-base --no-install-recommends
sudo apt-get install texlive-latex-base --no-install-recommends
sudo apt-get install texlive-latex-extra --no-install-recommends
sudo apt-get install texlive-lang-german --no-install-recommends
sudo apt-get install texlive-fonts-extra --no-install-recommends
```

`Make` and latexmk` is required for document generation.

## Generation via Make
The top level directory contains a Makefile.
Tor generation with all output formats use:

`````
make bundle
`````

The output files of the final handbook can be found in the subfolder `./bundle`.
All generated intermediate artifacts and the final output files can be found in the `./build` subfolder.

### Clean up

1. Deactivate the virtual Python environment: ```deactivate```
2. Clean up the build sources: ```make clean``` and ```rm -r build bundle```
