%% Purpose : The purpouse of the converter process is to take
%% care of the raw data that is received by the tracing
%% process (a pman_shell process) and pass it on to
%% the buffer process in chunks that can be handled.
%%
%% This module is a part of the buffering system, and
%% should not be used except through the API defined
%% in the pman_buf module.

%% Starts the process which received the raw data from the debugger,
