+AssRender is an AviSynth plugin that renders ASS/SSA and SRT (without the
+HTML-like markup) subtitles. It uses libass to render the subtitles, which makes
+it the fastest and most correct ASS renderer for AviSynth.

+This also means that it is much more picky about script syntax than VSFilter
+and friends, so keep that in mind before blaming the filter. Yes, people have
+reported a lot of errors that were actually the script author’s fault.
