positive.code: %% @doc NkSIP SIP basic message print and trace tool
  %%
  %% This module implements a simple but useful SIP trace utility. 
  %% You can configure any <i>SipApp</i> to trace SIP messages sent or received
  %% from specific IPs, to console or a disk file.
  %%
  %% It also allows to store (in memory) detailed information about 
  %% every request or response sent or received for debug purposes.
