I ran the `bin/console spdx --fix` with different strategies for
different files. For most of the core classes, since they've been
drastically rebuilt, I've run it with the `git-blame` strategy, for for
the `src/Validators`, in which the API changed completely but the logic
remains the same, I use the `git-log` strategy.
We had different ways of saving and loading files from `data/`, so I decided to
unify them to simplify things. I repurposed the `DomainInfo` class and named it
`DataLoader`, so we can use the same class to load anything from the `data/`
directory.
This commit introduces REUSE compliance by annotating all files
with SPDX information and placing the reused licences in the
LICENSES folder.
We additionally removed the docheader tool which is made obsolete
by this change.
The main LICENSE and copyright text of the project is now not under
my personal name anymore, and it belongs to "The Respect Project
Contributors" instead.
This change restores author names to several files, giving the
appropriate attribution for contributions.
It makes more sense to use PHP to generate PHP code than to use Bash. I
love writing Bash scripts, but I know it's not for everyone, and they
can become quite complex. Porting them to PHP code also lowers the
barrier for people to change them.
While I was making those changes, I also noticed a problem with how we
save the domain suffixes. We're converting all of them to ASCII, so we
are not preserving languages such as Chinese, Thai, and Hebrew, which
use non-ASCII characters.
