-# For example, if you pass 'test/foo' as a target name, your extension will
-# be installed under the 'test' directory. This means that in order to
-# load the file within a Ruby program later, that directory structure will
-# have to be followed, e.g. "require 'test/foo'".
-#
-# The +srcprefix+ should be used when your source files are not in the same
-# directory as your build script. This will not only eliminate the need for
-# you to manually copy the source files into the same directory as your build
-# script, but it also sets the proper +target_prefix+ in the generated
-# Makefile.
-#
-# Setting the +target_prefix+ will, in turn, install the generated binary in
-# a directory under your Config::CONFIG['sitearchdir'] that mimics your local
-# filesystem when you run 'make install'.
-#
-# For example, given the following file tree:
-#
-# ext/
-# extconf.rb
-# test/
-# foo.c
-#
-# And given the following code:
-#
-# create_makefile('test/foo', 'test')
-#
-# That will set the +target_prefix+ in the generated Makefile to 'test'. That,
-# in turn, will create the following file tree when installed via the
-# 'make install' command:
-#
-# /path/to/ruby/sitearchdir/test/foo.so
-#
-# It is recommended that you use this approach to generate your makefiles,
-# instead of copying files around manually, because some third party
-# libraries may depend on the +target_prefix+ being set properly.
-#
-# The +srcprefix+ argument can be used to override the default source
-# directory, i.e. the current directory . It is included as part of the VPATH
-# and added to the list of INCFLAGS.
