INSTALLATION
------------
All styles are written using LESS syntax. Thus it needs to be compiled
using the `lessc` (>= 2.5.2) command line tool. This comes with the `nodejs-less`
RPM package or using `npm install less` which depend on nodejs.
```
$ lessc --clean-css="--s1 --advanced" styles/styles.less > styles/styles.min.css
$ lessc --clean-css="--s1 --advanced" styles/print.less > styles/print.min.css
$ lessc --clean-css="--s1 --advanced" styles/embed.less > styles/embed.min.css
```
(`--clean-css="--s1 --advanced"` minifies the css, requires the clean-css Less plugin.
The plugin can be installed using `npm install less-plugin-clean-css`)
References to image files from the included CSS files can be appended
with cache-buster marks to avoid browser caching issues after updating.
Run `bin/updatecss.sh --dir skins/elastic` before packaging the skin
or after installing it on the destination system.
