In the Readme you can see the objective on this package.
* Generates one task compile for each extension you define in your Rakefile.
* Adds convention over folder structure and also adds the dependencies
between the files to avoid recompilation when is no need for it.
* It uses a temporary folder for you to inspect intermediate files
generated in the build process. (this also simplify the clean rules
about symbols and object files).
* simplifies end-user code, replacing long and duplicated across
project tasks to one-liners:
* It follows the same rules used by RubyGems when building the extensions
# ruby extconf.rb
# cp .so to lib/
So if something doesn't work with it, it definitely will not work with
your packaged gem.
* The possibility to generate binary gems with extensions bundled,
easing the binary release process.
* The possibility to extend this to cover Java (Rake::JavaJarTask) to
generate .jar packages.
Neither of these tasks and goals mess with the build generation by
itself. They only simplify the compilation and bundling.
Right now it only assumes extconf as configure script and make as
builder, but this could be changed in the configuration.
Human beings, who are almost unique in having the ability to learn from
the experience of others, are also remarkable for their apparent
disinclination to do so.
