Version 0.4.15 is a bug fix update for the Ruby 1.8.2 compatibility changes. This release includes:
Fixed a bug that prevented the TESTOPTS flag from working with the revised for 1.8.2 test task.
Updated the docs on –trace to indicate that it also enables a full backtrace on errors.
Several fixes for new warnings generated.
I will continue to issue Rake updates in the 0.4.xx series as new Ruby-1.8.2 issues become manifest. Once the codebase stabilizes, I will release a 0.5.0 version incorporating all the changes. If you are not using Ruby-1.8.2 and wish to avoid version churn, I recommend staying with a release prior to Rake-0.4.14.
Rake is a build tool similar to the make program in many ways. But instead of cryptic make recipes, Rake uses standard Ruby code to declare tasks and dependencies. You have the full power of a modern scripting language built right into your build tool.
