"""Override byte-compile sequence to catch any syntax error issue.
For some reason, distutils' byte-compile when it forks a sub-process
to byte-compile a .py file into a .pyc does NOT check the success of
the compilation. Therefore, any syntax error is explictly ignored,
and no output file is generated. This ends up generating an incomplete
package w/ a nevertheless successfull setup.py execution.
Here, each Python file is build before invoking distutils, so that any
syntax error is catched, raised and setup.py actually fails should this
event arise.
This step is critical to check that an unsupported syntax (for ex. 3.6
syntax w/ a 3.5 interpreter) does not end into a 'valid' package from
setuptools perspective...
