py_library.md

A re-implementation of py_library.

Supports "virtual" dependencies with a virtual_deps attribute, which lists packages which are required without binding them to a particular version of that package.

py_library(name, data, deps, imports, resolutions, srcs, virtual_deps)

ATTRIBUTES

Name	Description	Type	Mandatory	Default
name	A unique name for this target.	Name	required
data	Runtime dependencies of the program. The transitive closure of the data dependencies will be available in the .runfiles folder for this binary/test.
