List of labels; optional
The list of files needed by this rule at runtime.
Targets named in the data
attribute will appear in
the *.runfiles
area of this rule, if it has one. This
may include data files needed by a binary or library, or other
programs needed by it. See the
data dependencies section for more
information about how to depend on and use data files.
Almost all rules permit a data
attribute, but where
this attribute is not allowed, this fact is documented under the
specific rule.
