Sean Mooney had a good idea that for future-proofing the os-traits library and ensuring that we don't have to deal with one giant const.py file, that we break the library into various modules corresponding to the higher-level namespaces. This patch adds some symbol-registration foo into a utils module and allows the os_traits module and "leaf modules" to be called in the following way: import os_traits from os_traits.hw.cpu import x86 assert os_traits.HW_CPU_X86_SSE42 == x86.SSE42 assert x86.SSE42 == 'HW_CPU_X86_SSE42' Change-Id: I0e8f50822ab67cb3be85ed3b935dd6cdb4436dbf

:code:

|
mod_register('SSE')
