# Description:
#   The Boost library collection (http://www.boost.org)

# Most Boost libraries are header-only, in which case you only need to depend
# on :boost. If you need one of the libraries that has a separately-compiled
# implementation, depend on the appropriate libs rule.

# This is only needed for Avro.

上面的例子是从tenserflow的目录下, 找到一个比较短的例子.

这里我们可以看到有几个比较重要的关键字(这里的关键字意思和编程语言中的一样)

1. package
2. licenses
3. prefix_dir
4. cc_library
5. name
6. hdrs
7. src
8. glob
9. include
