# s6-rc-compile's input is a directory, but that doesn't play nice
# with Make, because it won't know to update if some file in the
# directory is changed, or a file is created or removed in a
# subdirectory.  Using the whole source directory could also end up
# including files that aren't intended to be part of the input, like
# temporary editor files or .license files.  So for all these reasons,
# only explicitly listed files are made available to s6-rc-compile.
