/*! \page page_ctrlport ControlPort
\section Introduction
This is the gr-ctroport package. It is a tool to create distributed
contol applications for GNU Radio. It provides blocks that can be
connected to an output stream to plot the signal remotely. It also
provides an API that allows blocks to export variables that can be
set, monitored, and plotted remotely.
The Python namespace is in gnuradio.ctrlport, which would be normally
imported as:
\code
from gnuradio import ctrlport
\endcode
See the Doxygen documentation for details about the blocks available
in this package. A quick listing of the details can be found in Python
after importing by using:
\code
help(ctrlport)
\endcode
\section Dependencies
ControlPort requires ZeroC's ICE and associated
libraries/headers/programs. ICE is generally installed into the
standard paths if using a software repo (like apt-get, yum, etc.). If
installed by hand, GNU Radio assumes ICE is installed into
/opt/Ice-3.4.2. If this is not the case, you can tell GNU Radio where
to find ICE by passing to cmake the following:
-DICE_MANUAL_INSTALL_PATH=\<your path here\>
\section conf Configuration
ControlPort is configured using two files. The first is the GNU Radio
preferences configuration while the second file is specific to the
type of transport engine used. Since we are focusing on using ICE, the
configuration file is the ICE configuration file and format.
The GNU Radio preferences file allows you to enable or disable
ControlPort. If enabled and a configuration file is used, this file
also specifies the location of the configuration file.
\code
[ControlPort]
on = True
config = ctrlport.conf
\endcode
The 'ctrlport.conf' holds specific properties related to the transport
engine. If using ICE, more information can be found here:
http://doc.zeroc.com/display/Ice/Properties+and+Configuration
An example ICE config file is installed with GNU Radio to show how to
change the exposed endpoint of ControlPort. This file is installed
as ${prefix}/etc/gnuradio/ctrlport.conf.example.
