Yes, tiOPF contains tiLog.pas unit and it's descendants. Even though your
project isn't based on tiOPF object model, the tiLog units are separated
and stand-alone, so you can us it in any application with ease.

tiOPF v2 includes:
  - Log to File
  - Log to Console
  - Log to FPC Debug Server
  - Log to System Log
  - Log to GUI Window
  - Log to Remote Server

...or any combination of the above.

I use the Log to GUI Window most. It also runs as a separate thread, and
logging is cached - so as not to slow down your application. At runtime you
see the window as your application starts. You can toggle at runtime which
log events you want to see (eg: Debug, Normal, Sql, Database connections,
Visitors etc...). There are many convenience functions for logging various
data types (eg: TtiObject, TStringList, TDataTime, String, Integer, Double,
etc..)

Due to the broken dbugintf (FPC/Lazarus Debug Server), and the
broken/unimplemented FPC DWARF2/3, and limited Object Pascl support by GDB,
an the many debugging limitations in Lazarus IDE, the tiOPF logging is by
far the most reliable. Setting up a few simple Code Templates make adding
log calls really quick.
