+The libisoburn installation described above produces a dynamically linked
+xorriso binary depending on libburn.so, libisofs.so, libisoburn.so.

+are present. This dependcy can be avoided by running

+If the output drive is not the input drive, and if it bears blank media
+or overwriteable without a valid ISO image, then one may produce a consolidated
+image with old and new data. This will copy file data from an eventual input
+drive with valid image, add any newly introduced data from the local
+filesystem, and produce a first session on output media.
+To prepare for such an image generation run, use isoburn_prepare_new_image().
+
+Blind Growing:
+This method reads the old image from one drive and writes the add-on session
+to a different drive. That output drive is nevertheless supposed to
+finally lead to the same media from where the session was loaded. Usually it
+will be stdio:/dev/fd/1 (i.e. stdout) being piped into some burn program
+like with this classic gesture:
+  mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev
+Blind growing is prepared by the call isoburn_prepare_blind_grow().
+The input drive should be released immediately after this call in order
+to allow the consumer of the output stream to access that drive for writing.

+    Create a disc object for writing an add-on session from the created or
+    loaded IsoImage which has been manipulated via libisofs, to a different
+    drive than the one from where it was loaded.
+    Usually output will be stdio:/dev/fd/1 (i.e. stdout) being piped
+    into some burn program like with this classic gesture:
+      mkisofs -M $dev -C $msc1,$nwa | cdrecord -waiti dev=$dev
+    Parameter translation into libisoburn:
+      $dev  is the address by which parameter in_drive of this call was aquired
+      $msc1 was set by isoburn_set_msc1() before image reading
+            or was detected from the in_drive media
+      $nwa  is a parameter of this call
+            or can be used as detected from the in_drive media
+
+    This call waits for libisofs output to become available and then detaches
+    the input drive object from the data source object by which libisofs was
+    reading from the input drive.
+    So, as far as libisofs is concerned, that drive may be released immediately
+    after this call in order to allow the consumer to access the drive for
+    writing.
+    The consumer should wait for input to become available and only then open
+    its burn drive. With cdrecord this is caused by option -waiti.
+  
+    The resulting burn_disc object has to be disposed when all its writing
+    is done and the drive is BURN_DRIVE_IDLE again after asynchronous
+    burn_disc_write().

+    @param in_drive The input drive,grabbed with isoburn_drive_scan_and_grab().

+Currently there is only one file format peculiar to xorriso : sector maps
+which describe the valid and invalid blocks on a media or a disk copy of
+a media. xorriso creates and reads these file with its option -check_media.
+
+The file begins with 32 bytes of cleartext of which the last one is a
+newline character. The first 25 say "xorriso sector bitmap v2 ", the
+remaining six characters give the size of the info text as decimal number.
+This number of bytes follows the first 32 and will not be interpreted
+by xorriso. They are rather to inform a human reader about the media type
+and its track layout.
+After the info text there are two 4 byte signed integers, most significant
+byte first. The first one, N, gives the number of bits in the following bitmap
+and the second number S gives the number of 2 KiB blocks governed by a single
+bit in the map. Then come the bits in form of 8-bit bytes.
+Data block M is covered by bit B=M/S in the map, bit number B is stored in
+byte B/8 as bit B%8. A valid readable data block has its bit set to 1.
