as listed in galaxyorbit.h.  New "-galaxy <first-galaxyorbit-coef>" option
enables it.  It compiles, but probably doesn't work yet.

parti.NNNN.log, where NNNN is the SZGClient ProcessID.
Maybe this too should be changed -- should we just try to log
to one big file, to limit clutter?  Every line is already labelled with [PID] now.

Don't use exit(0) in command parser.  Set a shared quit flag instead,
and have everybody (?) exit later.

<string>.append( C_string, len ) never copies in the string's trailing \000,
so add it ourselves.

Only create a listenSocket if we're the master -- avoid races to grab the port.
I'm not sure when is best to determine master-hood, so out of superstition
we do it in the first preExchange callback.

Yes, we *do* need to initialize cmdbuf_ to be *empty*.

szg gets mad if we try to select size 0.

in standalone ("warpsdb") mode.

Don't need giveup(), just expired().
Fix off-by-one error in consume().

properly earlier and (b) might have been changed by command-line I/O.
I.e. let the "run" command work if included in a .cf file.

Tidy list insert/deletion.
Call clock_tick() periodically in master to allow time to pass.
onPostExchange: Add more error checking.
main: Hack to allow running under Linux+freeglut in standalone mode.

for listening for commands from network;
transfer fields; attempts to get "play" to play, etc.
Some from Stuart: PpCmd uses string object;
passing PpCmd commands by transfer-field
from master to slaves.

and socket structures from Will Davis.
Update PpCmd to freeze commands into string objects.

in Syzygy case.

looks like a real bug, yeow.

Will Davis' changes:  No . before $(OBJ_SUFFIX).  Don't override .cc.o / .cpp.o rules.

Include Syzygy's $(COMPILE_FLAGS) in our $(CFLAGS)/$(CXXFLAGS).
For MinGW, need "-liberty" (for random()) and be sure to compile winjunk.c.

Explicitly (int) when we've parsed into a float.

according to whether msg() or warn() was called.

swap32() and swap16() return void.

onWindowStartGL() returns void.

Implement PpCmd interface for serializing commands for network transport.

Updated PpCmd interface too.
