### @usage: PY_SRCS({| CYTHON_C} { | TOP_LEVEL | NAMESPACE ns} Files...)
###
### Build specified Python sources according to Arcadia binary Python build. Basically creates precompiled and source resources keyed with module paths.
### The resources eventually are linked into final program and can be accessed as regular Python modules.
### This custom loader linked into the program will add them to sys.meta_path.
###
### PY_SRCS also support .proto, .ev, .pyx and .swg files. The .proto and .ev are compiled to .py-code by protoc and than handled as usual .py files.
### .pyx and .swg lead to C/C++ Python extensions generation, that are automatically registered in Python as built-in modules.
###
### By default .pyx files are built as C++-extensions. Use CYTHON_C to build them as C (similar to BUILDWITH_CYTHON_C, but with the ability to specify namespace).
###
### __init__.py never required, but if present (and specified in PY_SRCS), it will be imported when you import package modules with __init__.py Oh.
###
### @example
###
###     PY2_LIBRARY(mymodule)
###         PY_SRCS(a.py sub/dir/b.py e.proto sub/dir/f.proto c.pyx sub/dir/d.pyx g.swg sub/dir/h.swg)
###     END()
###
### PY_SRCS honors Python2 and Python3 differences and adjusts itself to Python version of a current module.
### PY_SRCS can be used in any Arcadia Python build modules like PY*_LIBRARY, PY*_PROGRAM, PY*TEST.
### PY_SRCS in LIBRARY or PROGRAM effectively converts these into PY2_LIBRARY and PY2_PROGRAM respectively.
### It is strongly advised to make this conversion explicit. Never use PY_SRCS in a LIBRARY if you plan to use it from external Python extension module.
