[Buildroot] [PATCH v2 4/4] pycompile: add --verbose option

[Yann E. MORIN <yann.morin.1998@free.fr>]

Robin, All,

On 2020-09-08 10:10 +0200, Robin Jarry spake thusly:
> Add a new option that prints the (runtime) path of compiled .py files
> when VERBOSE=1 is set.

I said in my reply to the cover letter that I had something to say about
that patch, but in fact no; it's pretty OK.

Just do not forget to switch to using str.format() instead of using the
old-style % formatting. ;-)

Regards,
Yann E. MORIN.
