+###
+### 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.
