Working on dvisvgm is fun but also time-consuming, even if it’s only a command-line program that might look like a small, simple application. However, under the hood, many complex components must properly work together in order to produce satisfying results. The implementation and improvement of the corresponding algorithms took and take a lot of time.
If you like dvisvgm and use it regularly, or if you simply want to support its improvement, please feel free to make a donation. All amounts are welcome and will help to keep the development going.
