Well, there is no such tutorial as far as I know. The code of log4cplus'
own appenders might work as one. Take a look at the NullAppender. It
shows the absolute minimum that you need to have for a valid appender.
Obviously, you will want to change the empty append() function to do
something useful.

As for registration, take a look at trunk or 1.1.0-RC6 source,
qt4debugappender.cxx. It has Qt4DebugAppender::registerAppender() which
shows what you need to do to register external appender into log4cplus::
name space. To register your appender into custom namespace use
something like this instead (untested):

log4cplus::spi::AppenderFactoryRegistry & reg
    = log4cplus::spi::getAppenderFactoryRegistry ();
LOG4CPLUS_REG_PRODUCT (reg, "MyNamespace::", MyAppender,
    MyNamespace::, log4cplus::spi::AppenderFactory)

Your properties files will then be able to instantiate your appender as
MyNamespace::MyAppender.
