description         multi-channel signed distance field generator
long_description    MSDFgen is a utility for generating signed \
                    distance fields from vector shapes and font \
                    glyphs, which serve as a texture representation \
                    that can be used in real-time graphics to \
                    efficiently reproduce said shapes. This is often \
                    applicable to, for example, using texture maps to \
                    represent \"line-art\" images, such as text, \
                    signs, and UI elements, that need to be rendered \
                    in real-time in computer games.
