From the developer:
t1lib is a library written in C which implements functions for generating bitmaps from Adobe Type 1 fonts. It uses most internal parts of the Type 1 rasterizer provided with X11R5 and newer but tries avoid the disadvantages known from that rasterizer. Although most people would use the rasterizer under X11, having X11 is not necessary at all.
