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
Path of a VBI device from which to read data.
Enables debug output: 0 = off (default); 1 = warnings, 2 = all messages.
Print a short description of all command line options.
