The multilog package requires only a recent fpc. It's also possible to 
use under Delphi (The Delphi executable sends the messages to a file or 
to a viewer compiled with Lazarus). The "high 3rd party requirement" is 
for the complete viewer. A simple viewer requires only Lazarus.

It can send messages through one or more channels. Currently its 
implemented the file and IPC (SimpleIPC) channels. Implementing a new 
(Console) channel is trivial. See the file channel.

It also provides several helper methods to control with fine granularity 
what messages to send. Some of then can be seen at 
http://code.google.com/p/luipack/wiki/MultiLog, but must of them are  
not documented. In the demos some other possibilities are explored.

As example, it's possible to restrict to send only the messages that are 
called below a method/function call stack.
Also the ability to attach a message to more than one class, together 
with the DefaultClasses and ActiveClasses property provides many ways to 
filter the messages, depending only of the imagination of the programmer.

I used a lot to debug event messages (generally recursive) in LCL. Even 
in fpGui  i used to debug the size behavior in Xlib/Win32 ;-).

Fell free to do it.
