Mickaël, All,

On 2019-10-30 17:17 +0100, Mickaël Tansorier spake thusly:
> Html page is generate by python script in `support/scripts/web-legal-info`.
> This script is called from Makefile at end of `legal-info` command.
> Output is `index.html` in legal-info subdirectory.
> This page contain informations about:
>  - buildroot config
>  - target packages: package name, version, licenses and sources
>  - host packages: package name, version, licenses and sources
> 
> This script need `legal-info` output path in arguments and it need files:
>   - `manifest.csv`
>   - `host-manifest.csv`
> `index.html` refers to other files in the legal-info directory:
>   - `buildroot.config`
>   - `sources/`
>   - `host-sources/`
>   - `licenses/`
>   - `host-licenses/`
> So only packages used to build image from config are listed.
> 
> Limitation: `web-legal-info` script depend of `legal-info` manifest format, output
> `*sources` folder structure and `*licenses` folder structure.

Sorry to come back so late on that old patch of yours. I provided some
(then-already late and typo-ridden) feedback more than a year ago, and
we rediscussed this recently with the other maintainers, and we decided
to not apply this patch.

Sorry again for this long hiatus before eventually coming to a
conclusion...

Thank you!

Regards,
Yann E. MORIN.
