ftrandom
---------
+========
This program expects a set of directories containing good fonts, and a set
of extensions of fonts to be tested. It will randomly pick a font, copy it,
-introduce and error and then test it.

- --rasterize Call FT_Render_Glyph as well as loading it.

+ This is done in the current process so it can be
+ debugged more easily.
+
+The default font extensions tested by ftrandom are
+
+ .ttf .otf .ttc .cid .pfb .pfa .bdf .pcf .pfr .fon .otb .cff
+
+The default font directory is controlled by the macro `GOOD_FONTS_DIR' in
+the source code (and can be thus specified during compilation); its default
+value is
+
+ /usr/local/share/fonts
+
+The default result directory is `results' (in the current directory).
+
+
+Compilation
+-----------
+
+Two possible solutions.
+
+. Run ftrandom within a debugging tool like `valgrind' to catch various
+ memory issues.
+
+. Compile FreeType with sanitizer flags as provided by gcc or clang, for
+ example, then link it with ftrandom.
