+# Tool to embed file into objects
+
+__author__ = __maintainer__ = "Jérôme Carretero <cJ-waf@zougloub.eu>"
+__copyright__ = "Jérôme Carretero, 2014"
+
+"""
+
+This tool allows to embed file contents in object files (.o).
+It is not exactly portable, and the file contents are reachable
+using various non-portable fashions.
+The goal here is to provide a functional interface to the embedding
+of file data in objects.
+See the ``playground/embedded_resources`` example for an example.
+
+Usage::
+
+   bld(
+    name='pipeline',
+     # ^ Reference this in use="..." for things using the generated code
+    features='file_to_object',
+    source='some.file',
+     # ^ Name of the file to embed in binary section.
+   )
+
+Known issues:
+
+- Destination is named like source, with extension renamed to .o
+  eg. some.file -> some.o
