NAME
       zvbi-chains - VBI proxy wrapper


SYNOPSIS
       zvbi-chains [ options ]


DESCRIPTION
       zvbi-chains  is  a  small  wrapper  which  executes  the  VBI application given on the command line while
       overloading several C library calls (such as open(2) and read(2)) so that the application can  be  forced
       to access VBI devices via the VBI proxy instead of device files directly.

       LD_PRELOAD  is  used  to intercept C library calls and call functions in the libzvbi-chain shared library
       instead. Parameters given on the command line (e.g. device path) are passed to the library  by  means  of
       environment variables.


OPTIONS
       -dev path
              Path of a VBI device from which to read data.

       -debug level
              Enables debug output: 0 = off (default); 1 = warnings, 2 = all messages.

       -help  Print a short description of all command line options.
