## $LESSOPEN

`much` supports `$LESSOPEN` variable in the same manner as `less(1)`. This allows for preprocessing step before pager displays file contents. See `less(1)` manual for details.

For example, include the following line in the shell config to highlight files with `source-highlight(1)`:

```bash
LESSOPEN="| src-hilite-lesspipe.sh %s"
```

## Install

```shell
npm install -g much
```
