Log4r works really well, so please take advantage of it right away! :)
All versions since 0.9.2 have been stable and backward-compatible. The
code is stable enough that updates are infrequent and usually only for
adding features or keeping the code up to date with Ruby.
Platform Issues
Log4r is known to work on Linux and WindowsXP. It's safe to assume that Log4r
will work on any Ruby-supported platform.
When Trouble Strikes
Log4r comes with an internal logger. To see its output, create a logger
named 'log4r' before any others and give it a suitable outputter,
trouble =['log4r']
trouble.add Outputter.stdout
Try running the unit tests provided (run the file tests/runtest.rb). Let
the maintainer know what's up and feel free to explore and fix the
code yourself. It's well documented and written in Ruby. :)
