+We are quite sure that libisofs produces accurate representations of the disk
+files. This opinion is founded on a lot of tests burns and checks by a little
+test program which compares files from the mounted image with the orignals
+on disk. It uses the normal Linux filesystem calls, i.e. no libburnia stuff.
+
+This program is not installed systemwide but stays in the installation
+directory of the xorriso tarball as  test/compare_file . Usually it is
+run as -exec payload of a find command. It takes three arguments:
+The file path of the first file to compare, the prefix1 to be cut off from path
+and the prefix2 which gets prepended afterwards to obtain the path of the
+second file to compare.
+
+To compare tree /media/dvd and /original/dir :
+   find /original/dir -exec compare_file '{}' /original/dir /media/dvd ';' \
+   | less
+and:
+   find /media/dvd -exec compare_file '{}' /media/dvd /original/dir ';' | less
