3"""buildpkg.py -- Build OS X packages for Apple's Installer.app.
4
5This is an experimental command-line tool for building packages to be
6installed with the Mac OS X Installer.app application.
7
8It is much inspired by Apple's GUI tool called PackageMaker.app, that
9seems to be part of the OS X developer tools installed in the folder
10/Developer/Applications. But apparently there are other free tools to
11do the same thing which are also named PackageMaker like Brian Hill's
12one:
13
14 http://personalpages.tds.net/~brian_hill/packagemaker.html
15
16Beware of the multi-package features of Installer.app (which are not
17yet supported here) that can potentially screw-up your installation
18and are discussed in these articles on Stepwise:
19
20 http://www.stepwise.com/Articles/Technical/Packages/InstallerWoes.html
21 http://www.stepwise.com/Articles/Technical/Packages/InstallerOnX.html
22
23Beside using the PackageMaker class directly, by importing it inside
24another module, say, there are additional ways of using this module:
25the top-level buildPackage() function provides a shortcut to the same
26feature and is also called when using this module from the command-
27line.
28
29 ****************************************************************
30 NOTE: For now you should be able to run this even on a non-OS X
31 system and get something similar to a package, but without
32 the real archive (needs pax) and bom files (needs mkbom)
33 inside! This is only for providing a chance for testing to
34 folks without OS X.
35 ****************************************************************
36
37TODO:
38 - test pre-process and post-process scripts (Python ones?)
39 - handle multi-volume packages (?)
40 - integrate into distutils (?)

122 This is intended to create OS X packages (with extension .pkg)

125
126 As of now, PackageMaker instances need to be created with the
127 title, version and description of the package to be built.
128 The package is built after calling the instance method
129 build(root, **options). It has the same name as the constructor's
130 title argument plus a '.pkg' extension and is located in the same
131 parent folder that contains the root folder.
