+
+  By friday (2005.10.07), I managed to get the update process
+  working well, and tested it with some example data to demonstrate
+  that the partial update improved speed hugely.  Saturday, I started
+  to work on the client/server separation of addstar.  The first step
+  was to test out socket communication issues.  I set up a simple
+  client/server pair, in which one program listens on a socket while
+  the client connects to the socket and sends some command.  I set up
+  two autocode functions to send and receive complete structures
+  (Send_*, Recv_*) and added these to libautocode.  I have been able
+  to demonstrate sending Stars, Image, and Options to the server.
+
+  The next difficulty is in pulling out the command-line and
+  configuration options.  My original, somewhat lazy, design over-used
+  global variables to pass information between program sections.  This
+  needs to be cleaned up, especially if the server needs to have
+  multiple threads interacting with the db tables.  
+
+  Of the global variables that get set, some simply carry options on
+  how gstars should behave when it loads the data (including the
+  header interpretation information).  This can probably stay in the
+  globals for now.  Another group are configuration information used
+  only by the server-related functions, such as defining the location
+  of the database files and their format, etc.  These can also stay as
+  global, at least for now.  Another set of variables basically pass
+  information from the client to the server on how to behave *this
+  time*.  I have defined the AddstarClientOptions structure to carry
+  these, and will pass them from the client to the server along with
+  the stars and the image data.
+
+  Some outstanding issues:
+
+  sidereal time / latitude
+
+  I am carrying these as globals simply because the image structure
+  did not have them.  This is silly: I can define them as part of the
+  internal image structure without breaking any of the I/O issues.  
+
+  thiscode
+
+  I have been using this as a static photcode structure.  The
+  Send_*/Recv_* mechanisms are better suited to simple structures.  I
+  probably need to change this to just the code, and use the lookup
+  functions to the full structures where needed.  It can be part of
+  the options, and I should re-write functions which use it to accept
+  the options as an argument rather than rely on it as a global.
+
+  mosaic
+
+  this stores the coords structure for a needed mosaic.  this should
+  be kept, filled as needed by the client, and sent to the server with
+  the image.  perhaps it can be moved out of global.
