## Build and Install (for Distributor) ##


* To build the style file `sunpath.sty` just run **one** of

```
latex sunpath.ins
pdflatex sunpath.ins
xelatex sunpath.ins
lualatex sunpath.ins
```

then you can copy `sunpath.sty` to your local `texmf` tree, where latex can find it.

* To create PDF Document manual you must use `lualatex` via `l3build doc`:

```
l3build doc
```

You also need the TikZ-library hobby to create the curve.

```
\usetikzlibrary{hobby}
```

(`lualatex` because of my name, really ego right! It needs unicode to be typeset correctly.)

## Development ##


I try to use latex3 as much as posible. You can use 

```
l3build doc
```

to create the style file and documentation files at once. You can also (like I also do) use `make`
to call repeatly tasks.
