+ # Create a build task that will generate a Ruby extension (e.g. .so) from one or more
+ # C (.c) or C++ (.cc, .cpp, .cxx) files, and is intended as a replcaement for mkmf.
+ # It determines platform-specific settings (e.g. file extensions, compiler flags, etc.)
+ # from rbconfig (note: examples assume *nix file extensions).
+ #
+ # *Note*: Strings vs Symbols
+ # In places where filenames are expected (e.g. lib_name and objs), Strings are used
+ # as verbatim filenames, while, Symbols have the platform-dependant extension
+ # appended (e.g. '.so' for libraries and '.o' for objects). Also, only Symbols
+ # have #dir prepended to them.
+ #
+ # Example:
+ # desc "build sample extension"
+ # # build sample.so (from foo.{c,cc,cxx,cpp}, through foo.o)
+ # Rake::ExtensionTask.new :sample => :foo do |t|
+ # # all extension files under this directory
+ # t.dir = 'ext'
+ # # link libraries (libbar.so)
