Option 1: (recommended for multiple single file binaries)

use preBuildCommands to invoke dub or dmd for each of your 
scripts you need

Compatibility tip: use the special $DUB and $DC variables, see

If built often, consider using rdmd for easy caching or make this 
a sub-package which you depend on which will therefore only be 
rebuilt in case of changes to that sub-path folder. Add a glob of 
"extraDependencyFiles" matching your script files to make the 
package rebuild on script changes.

Option 2: (recommended for multiple larger binaries)

use sub-packages and make your root package targetType: none to 
build all child packages, see

root dub.sdl:
name "test"
targetType "none"
dependency ":a" version="*"
dependency ":b" version="*"
subPackage "a"
subPackage "b"

name "a"
targetType "executable"

name "b"
targetType "executable"

$ dub build


Note: this only works if your package is targetType none, use 
targetName and targetPath to customize how the exe is called and 
where it's placed
