timblclient

timblclient(1)						      General Commands Manual						    timblclient(1)

NAME

       timblclient - a simple client to access the Tilburg Memory Based Learner Server

SYNOPSYS

       timblclient -h host -p port [-i inputfile] [-i outputfile] [--batch] [-b basename]

DESCRIPTION

       timblclient connects to a TimblServer on 'host':'port' and sends it the normal instructions. (see timblserver )

OPTIONS

       The timblclient options are

       -i inputfile
	      a series of timblserver commands.

	      When  BATCH  is  specified, inputfile is supposed to be a 'normal' Timbl testfile. Every line is send to the timblserver as a 'clas-
	      sify' command.  Default is stdin.

       -o outputfile
	      Where to put the results. Default is stdout.

       --batch
	      When --batch is specified, the input from 'inputfile' is not interpreted as timblserver commands, but as instances that will be send
	      'as is' prepended by a classify instruction.

       -h host
	      connect to the server on 'host'

       -p port
	      connect to 'port' on 'host'

       -b basename
	      set the base in TimblServer to 'base'

BUGS

       This is just a simple testprogram, and rather clumsy.
