The python module that should be the entry point of the binary. This should be a module name within a python_library that this binary depends on. Note that module names take
base_moduleof the library into account. This property is mutually exclusive with
main, and should be preferred to
main, which is deprecated.
The Python file which serves as the entry point for the PEX. The interpreter initiates execution of the PEX with the code in this file.
The package in which the main module should reside in its final location in the binary. If unset, Buck uses the project-relative directory that contains the BUCK file.

A list of
python_libraryrules that specify Python modules to include in the PEX file—including all transitive dependencies of these rules.
A list of C/C++ library dependencies that need to be loaded before any other libraries when the PEX starts up. This requires dynamic loader support, such as
LD_PRELOAD, found on most systems. This list is order- sensitive and the preload libraries listed here are passed down to the dynamic linker in the same order.
