svgsprite
This is a simple script (no external dependencies) to regroup all the SVG files from a directory into a single sprite.
Installation
pip install svgsprite
Usage
svgsprite --src path/to/dir/with/svg/files --dest path/to/sprite/to/create
You can then refer to your icons with tags like this:
<svg>
<use xlink:href="sprite.svg#my-svg-file"></use>
</svg>
