Retrieves logs from 9 days ago until today and only outputs results if there are matches for the day. Setting the time zone to that of Germany works on Linux and may work on MacOS but has not been tested. Setting the time zone on your machine to Europe/Berlin before running this code will take care of the issue no matter what operating system you're using.

Currently Wren CLI does not have methods to download files or even determine the current date/time in its standard library.
However, it is designed to be used primarily as an embedded scripting language and we can therefore ask the host (in this case a C program) to call the necessary functions from its own libraries and pass the results back to Wren. We can then manipulate the date using the above module, search the downloaded files for the string in question and print the results.

We now embed this in the following C program, build and run. Note that, whilst it would be possible to embed the Wren script ''directly'' into the C program (so there's only a single file), we have refrained from doing so in the interests of clarity.

While zkl supports TCP natively and talking simple HTTP is easy,
Curl is way easier and fully supports the protocol.
