PicoLibC

[J05HYYY]

Hi,

This software has about a bazillion different licences:

https://github.com/picolibc/picolibc/blob/main/COPYING.picolibc

I am avoiding it's use at present because I don't know if it's free
software or not.

I am able to check a small number of licences manually, but I am not a
lawyer, so I don't know if some of the terms in the licences are
restrictive or not, ie. I can't say definitively.

There are some custom licences within the software.

I was wondering,

1) Is this software is free software?
2) Is there an automated way of telling which licences and files are
free and non-free within a project ... like using a database of
licences ... I've heard of a licence-check script but I'm not sure if
it does that.

Thanks,

Josh
