Sometimes you need other stuff in your applications like a third-party library, some data files, a script or a legacy program built on another system.

To add other files to applications, you add other sections to your application's ".adef" file.

Here's a sample of how to add an audio file and a third-party library:

files:
    [r]     audio/alert.wav     /usr/share/sounds/
    [r]     third-party/foo/lib/foo.so.1 /lib

The "files:" section will get the file ./audio/alert.wav from the build host's file system (relative to the current working directory in which mkapp is run), and list it under /usr/share/sounds (from the application's point-of-view when it runs on the target).

The letter inside the square brackets (e.g., [r]) contain the permissions flags for the file on the target:

'r' = readable
'w' = writeable but changes will be discarded on reset
'x' = executable

If you want to have a script or other executable run when the application starts, add that file to

the "files:" section (with the executable flag [x] set), and
the list of executables in the processes section, "run:" subsection.

files:
    [x]     otherProject/bin/bar    /usr/bin/bar
processes:
run: (/usr/bin/bar)

This grabs ./otherProject/bin/bar (relative to the directory where mkapp is run), displays it in the application sandbox's /usr/bin/bar directory, and starts one instance of it when the application starts.
