Great to see another release. Regarding the MP4/ASF support in 1.6, is
there a way to detect for a program using taglib to detect whether
support is buildin or not (runtime and compiletime)? Since I access the
mp4 tag to check for disc numbers, I guess my program depends on some of
the mp4 dependent header files. Will those be installed when mp4/asf is

How much does the ASF/MP4 support differ from taglib-extras ?
