hu-berlin-bundle
================

This package provides files according to the corporate design
for the Humboldt-Universität zu Berlin.
It is _no_ official package of the university itself and
not officially approved by it.

You find more information in the official [corporate design guideline](https://www.hu-berlin.de/de/hu-intern/design/basiselemente/leitfaden-corporate-design-hu.pdf) 
and on the website <https://www.hu-berlin.de/de/hu-intern/design>.

## Documents and Documentations for hu-berlin bundle


This bundle provides following files:

  * `hu-berlin-bundle.dtx` which is the core file designed with literate programming 
  * `hu-berlin-bundle.ins` which is the installation file for all necessary files generated automatically
  * `hu-berlin-bundle.pdf` is documentation of the bundle.
  * `README.md`
  * `makefile`

All other files can and will be generated from the `.dtx` file (see below).

Furthermore there is the folder `img` which contains the necessary image files.


This work has the LPPL maintenance status _maintained_.
The current maintainer of this work is [Lukas C. Bossert](https://github.com/lukascbossert).


You find this bundle versioned and available on [Zenodo](https://doi.org/10.5281/zenodo.3251728)

With this (unofficial) bundle you have several documents which are designed according to the corporate design of the Humboldt-Universität zu Berlin.


Following documents or documentclasses are available:

* letter (`hu-berlin-letter.cls`); via `.tex` and `.md`
* base package (`hu-berlin-base.sty`)


## Installation of the bundle
`hu-berlin` is part of the distributions [MiKTeX](http://www.miktex.org)
and [TeXLive](http://www.tug.org/texlive) -- thus, you
can easily install it using the respective package manager.
If you would like to
install `hu-berlin-bundle` into your local folder  manually, do the following:
Go to your terminal, browse to the folder of this bundle and run

```
make install
```


If you are using macOS you might be asked for your user account password for the installation.


Further options of this makefile are:

* `clean`:  deletes all unnecessary files
* `cleanbundle`:  deletes all files except `.dtx`, `.md`. You will get the plain version of this bundle.
This might be helpful if you send the bundle to someone else.
* `ctan`:  this will create a zip file which can be used to send to CTAN.
* `files`: will only create the files from the `.dtx`-scratch.
* `uninstall`: will erase the locally installed files.


This bundle is constantly updated. For hints, errors or suggestions use the GitHub repository [https://github.com/LukasCBossert/hu-berlin-bundle](https://github.com/LukasCBossert/hu-berlin-bundle).

## Changelog

All notable changes to this project will be documented in the [README.md](https://github.com/LukasCBossert/hu-berlin-bundle/blob/master/README.md).
This project **does not** adhere to [Semantic Versioning](http://semver.org/).
The markdown syntax is inspired by the conventions proposed by [keepachangelog.com](http://keepachangelog.com/).

### v1.0.4 (2019-12-19)
* Added `hu-berlin-base.sty` as a package which contains all relevant code for documents and documentclasses of the bundle.

### v1.0.3 (2019-06-26)
 * Changed the main font for compatibility with UNIX-systems (TeX Gyre Heros instead of Verdana).
 
### v1.0.2 (2019-06-22)
 Renaming files for CTAN compatability.


### v1.0.1 (2019-06-21)
 Internal changes for publishing. Still one documentclass for a letter.

### v1.0.0 (2019-06-21)
 First release with a documentclass for letter.

## Copyright
Various parts of this bundle have different copyrights.
If not otherwise stated the copyright is [The LaTeX project public license (LPPL), version 1.3c](https://www.latex-project.org/lppl/lppl-1-3c/)


### Boilerplate / markdown-template
The template for the markdown conversion, 
forked from the pandoc-templates and [JensErat pandoc-scrlttr2](https://github.com/JensErat/pandoc-scrlttr2) is dual-licensed,
