+"""buildpkg.py -- Build OS X packages for Apple's Installer.app.
+
+This is an experimental command-line tool for building packages to be
+installed with the Mac OS X Installer.app application. 
+
+It is much inspired by Apple's GUI tool called PackageMaker.app, that 
+seems to be part of the OS X developer tools installed in the folder 
+/Developer/Applications. But apparently there are other free tools to 
+do the same thing which are also named PackageMaker like Brian Hill's 
+one: 
+
+  http://personalpages.tds.net/~brian_hill/packagemaker.html
+
+Beware of the multi-package features of Installer.app (which are not 
+yet supported here) that can potentially screw-up your installation 
+and are discussed in these articles on Stepwise:
+
+  http://www.stepwise.com/Articles/Technical/Packages/InstallerWoes.html
+  http://www.stepwise.com/Articles/Technical/Packages/InstallerOnX.html
+
+Beside using the PackageMaker class directly, by importing it inside 
+another module, say, there are additional ways of using this module:
+the top-level buildPackage() function provides a shortcut to the same 
+feature and is also called when using this module from the command-
+line.
+
+    ****************************************************************
+    NOTE: For now you should be able to run this even on a non-OS X 
+          system and get something similar to a package, but without
+          the real archive (needs pax) and bom files (needs mkbom) 
+          inside! This is only for providing a chance for testing to 
+          folks without OS X.
+    ****************************************************************
+
+TODO:
+  - test pre-process and post-process scripts (Python ones?)
+  - handle multi-volume packages (?)
+  - integrate into distutils (?)
