  23  * Some notes on the history of this project/code/copyrights:
  24  *
  25  *  - the project is called SIPE, but originally the code was only written
  26  *    for the libpurple framework, i.e. Pidgin. Hence the package name is
  27  *    "pidgin-sipe".
  28  *
  29  *  - in the beginning almost all of the code was located in a module
  30  *    called "sipe.c". During the effort to remove the libpurple
  31  *    dependencies from the SIPE core, thousands of lines of code got
  32  *    shifted out of sipe.c, mostly to newly created modules and sipe.c
  33  *    ceased to exist.
  34  *
  35  *  - it would have been tedious to track down the original author or
  36  *    copyright and preserve them for each line of code that was moved.
  37  *    Therefore the new modules started with a fresh copyright notice
  38  *    (like the one above).
  39  *
  40  *  - the original copyright notices from sipe.c have been moved to this
  41  *    file (see below) and *MUST* be preserved!
  42  *
  43  *  - if necessary the author of a line of code in question can still be
  44  *    reconstructed from the git repository information.
  45  *    See also "man git-blame"
  46  *
  47  *  - if you think your copyright should be restored for a piece of code,
  48  *    then please contact the SIPE project to fix the source files ASAP.
