# jlreq

## What is this?
This package provides the class file and JFM (Japanese font metric) files for LuaTeX-ja / pLaTeX / upLaTeX. This aims to implement [Requirements for Japanese Text Layout](https://www.w3.org/TR/jlreq/?lang=en).

## Installation
Run `make` to generate JFM files. Move the files as follows:

* *.tfm -> $TEXMF/fonts/tfm/public/jlreq
* *.vf -> $TEXMF/fonts/vf/public/jlreq
* jfm-jlreq.lua, jfm-jlreqv.lua, jfm-jlreq-jidori.lua jfm-jlreqv-jidori.lua -> $TEXMF/tex/luatex/jlreq
* jlreq.cls, jlreq-helpers.sty  -> $TEXMF/tex/latex/jlreq

The other way to install is just to run `make install`. It will install all files in `$TEXMFHOME`.

## Usage
See [README-ja.md](README-ja.md) (in Japanese).
