- Creation or post-processing of `.desktop` files
- Installation of AppStream metadata
- Defining the location for application icons

This module is available on all platforms but is currently only useful on UNIX platforms.

### Example usage

     Application {
         ...
         Depends { name: "freedesktop" }

         Group {
             files: [
                 ...

                 // Declare the desktop and appstream files
                 "data/my-app.desktop",
                 "data/my-app.metainfo.xml",
             ]
         }

         // Add/change some fields in the desktop file
         freedesktop.desktopKeys: ({
             'Exec': FileInfo.joinPaths(qbs.installPrefix,
                                        product.installDir,
                                        product.targetName) + ' --argument',
             'X-Application-Version': product.version,
         })

         // Declare the application icon
         Group {
