+File Format
+=============
+
+This is the format of the package and manifest files used by the Auto-Updater.
+
+
+Package File
+--------------
+
+This file type is used to transport files for installation or update.
+
+It is recommended to put each component into one separate package - e.g. one
+for the actual application, one for plugins, one for Qt, etc. - this way it is
+easier to do partion (security) updates.
+
+All numbers are 32bit big endian.
+
+Pos. Len. Content
+0000  4   Magic Bytes 0x552d3837
+0004  4   Version Number: 0x000100 (i.e. 0.1.0)
+0008  4   Amount of Directory entries
+000c  *   compressed files
+
+Per Directory entry:
+0000  4   Length of Filename
+0004  4   Length of File compressed (0 indicates empty file or a directory)
+0008  *   Filename in UTF-8 encoding
+ n+8  *   Packed file (non-existent if length indicated 0)
+
+Notes on Filenames:
+* the directory separator is "/"
+* components that consist of dots only make the file name illegal
+* illegal file name means the file is ignored with a warning
+* leading "/" is ignored, leading drive letter (Regexp: "[a-zA-Z]:")
+* directory names end in "/"
+* executable files end in "*" - the "*" is stripped off
+
+Manifest File
+---------------
+
+This file type describes which package files are needed for a specific
+installation version and contains the Signature and Keys.
