Detailed Description

A description of the expected file structure of a given package type.

PackageStructure defines what is in a package. This information is used to create packages and provides a way to programatically refer to contents.

An example usage of this class might be:

    PackageStructure structure;

    structure.addDirectoryDefinition("images", "pics/", i18n("Images"));
    QStringList mimetypes;
    mimetypes << "image/svg" << "image/png" << "image/jpeg";
    structure.setMimetypes("images", mimetypes);

    structure.addDirectoryDefinition("scripts", "code/", i18n("Executable Scripts"));
    mimetypes.clear();
    mimetypes << "text/\*";
    structure.setMimetypes("scripts", mimetypes);

    structure.addFileDefinition("mainscript", "code/main.js", i18n("Main Script File"));
    structure.setRequired("mainscript", true);

One may also choose to create a subclass of PackageStructure and include the setup in the constructor.

Either way, PackageStructure creates a sort of "contract" between the packager and the application which is also self-documenting.

path	the path within the package for this directory
name	the user visible (translated) name for the directory
