+    Due to copyright reasons we don't include full typesets into
+    the swftools package. But you can easily create fontdumps
+    of your desired typo:
+
+    * Create a swf file with all characters of your desired fonts
+      (with any tool that can output swf files)
+
+    * use the dumpfont example in this directory to dump font code
+
+    * include dump code and adjust Font_<Fontname>() calls.
+
+    Note: pdf2swf (Version 0.1.0) doesn't write ST_DEFINEFONTINFO tags,
+    so you can't extract fonts out of documents made with pdf2swf.
