# The syntax is

#           commands...
#       } {
#           variables...
#       } 
#
# Registers a server by <name> at port <port>.
# When a connection is made to <port>, <command> is run.
# Environment variables will be set before executing command.  
#
# Note: Don't set DISPLAY here. nanoscale itself sets the DISPLAY
#       variable.
#
# Defaults:
#   o Server reads from file descriptor 0.
#   o Server writes to descriptor 1.
#   o Server stdout and stderr are redirected to a log file.

# Notes: 
#       o Continue to use default options until we offically upgrade

#         version of nanovis.
#       o Requires change to 1.2 nanovis.  Can't redirect stderr to log

# Notes:
#       o Removed ${vtkdir} from LD_LIRBRARY_PATH. Not needed with VTK 6.
#       o Using new features in nanoscale/vtkvis to use file descriptor 3
#         for server output.  No automatic logging of stdout and stderr.

# Notes:
#       o Need PYMOL_SITE_PATH for parallelpiped box.py location.
#       o Makes no sense to log stdout and stderr of the proxy.
#       o Renamed to just pymolproxy and removed non-threaded entry.

# VmdShow -- 
#       Server type     Molecular layouts using VMD viewer (for mdshowcase).
#       Port            2018
#       Threaded        no
# Notes:
#       o Commands are sent directly to the VMD process that uses custom
#         TCL code to process.
#       o Redirect input to descriptor 3: Otherwise VMD will get select hit.
#       o Redirect output to descriptor 4: Lots of information written to
#         stdout and stderr of VMD.  Captured in log file.
#       o Executing binary without wrapper shell script. Requires VMDDIR set.
#       o Meshing programs surf and msms require explicit environment variables.
#       o __GL_SYNC_TO_VBLANK probably doesn't matter.
#       o Client doesn't send data files to VMD, but file paths.  Unlikely
#         client will block on a large write.
