       owfs.conf - owfs programs configuration file


       An OWFS configuration file is specified on the command line:

       owfs -c config_file [other options]
              The file name is arbitrary, there is no default configuration file used.


       A  configuration  file  can be invoked for any of the OWFS programs ( owfs (1) owhttpd (1)
       owserver (1) owftpd (1) ) or any of the language bindings ( owperl (1)  owcapi  (1)  owtcl
       (1) owphp owpython ) to set command line parameters.


       Similar to Unix shell script or perl syntax

              # blank lines are ignored

              option # some options (like 'foreground') take no values
              option = value # other options need a value
              option value # '=' can be omitted if whitespace separates
              Option # Case is ignored (for options, not values)
              opt # non-ambiguous abbreviation allowed
              -opt --opt # hyphens ignored

              server: opt = value # only owserver effected by this line

       1-wire  is  a  wiring  protocol  and series of devices designed and manufactured by Dallas
       Semiconductor, Inc. The bus is a low-power low-speed low-connector scheme where  the  data
       line can also provide power.

       Each  device  is  uniquely  and  unalterably numbered during manufacture. There are a wide
       variety of devices, including memory, sensors (humidity,  temperature,  voltage,  contact,
       current),  switches,  timers  and  data  loggers.  More complex devices (like thermocouple
       sensors) can be built with these basic devices. There are also 1-wire  devices  that  have
       encryption included.

       The  1-wire  scheme uses a single bus master and multiple slaves on the same wire. The bus
       master initiates  all  communication.  The  slaves  can  be  individually  discovered  and
       addressed using their unique ID.

       Bus  masters  come in a variety of configurations including serial, parallel, i2c, network
       or USB adapters.

   OWFS design
       OWFS is a suite of programs that designed to make the 1-wire bus and  its  devices  easily
       accessible. The underlying principle is to create a virtual filesystem, with the unique ID
       being the directory, and the individual properties of the device are represented as simple
       files that can be read and written.

       Details of the individual slave or master design are hidden behind a consistent interface.
       The goal is to provide an easy set of tools for a software designer to  create  monitoring
       or  control  applications.  There are some performance enhancements in the implementation,
       including data caching,  parallel  access  to  bus  masters,  and  aggregation  of  device
       communication.  Still  the  fundamental  goal  has  been  ease  of  use,  flexibility  and
       correctness rather than speed.

       owfs.conf (5) allows a uniform set of command line parameters to be set.

       Not all OWFS programs use the same command line options, but the non-relevant ones will be

       Command  line  and  configuration  options  can  mixed.  They will be invoked in the order
       presented. Left to right for the command line. Top to bottom for the configuration file.

       Configuration files can call other configuration files. There is an arbitrary depth  of  5
       levels to prevent infinite loops. More than one configuration file can be specified.


       Here is a sample configuration file with all the possible parameters included.
