How can I preserve the attributes for the files with resource forks?

In some cases, when building installer for OS X platforms, you may need to add the piece of code below in your xml project in order to correctly preserve the attributes for the file with resource forks.

<postInstallationActionList>
 ...
 <changeOSXAttributes creator="creator_code" files="${installdir}/path/to/your/file" type="application_type" />
 ...
 </postInstallationActionList>

You can get the right attributes values for creator and type using the GetFileInfo tool:

/Developer/Tools/GetFileInfo /path/to/your/file
