-Generates a static HTML page with a list of all the leases allocated by `dnsmasq`.
-
-A simple template written in the jinja syntax is used.
-
-The file containing the leases is expected to be at `/var/lib/dnsmasq/dnsmasq.leases`, but this can be overwritten by setting the environment variable `DNSMASQ_LEASES`.
-
-The output of the script is written to `/var/lib/dnsmasq/leases.html` by default, but the destination can be overwritten by setting the environment variable `DNSMASQ_LEASES_OUT`.
-
-The script can be executed automatically by `dnsmasq` if the configuration for `dhcp-script` is set to the path of the script. This will only be executed when a *new* lease is created or an *old* lease is deleted. To execute the script when a lease is *updated* you need to use the configuration `script-on-renewal`.
-
-A configuration looks like this:
-
-``` ini
-dhcp-script=${pkgs.tools.dnsmasq-to-html}/bin/dnsmasq-leases-html
-script-on-renewal
-```
-
-## nginx
-To serve the page with nginx, you can use the following configuration:
-
-``` nix
-services.nginx = {
-  enable = true;
-  virtualHosts."dnsmasq" = {
-    listen = [
-      {
-        addr = "192.168.6.1";
-        port = 8067;
-      }
-    ];
-    locations."/" = {
-      root = "/var/lib/dnsmasq";
-      index = "leases.html";
-    };
-  };
-};
-```

-the tool takes a couple of arguments:
-- ~-dest~: where will the music be stored
-- a list of directories to scan
-
-all files that have tags that can be read will be processed and moved to the specified destination.
-
-files are organized like this: ={artist}/{album}/{track number} {track title}.{track format}=
-
-the tool ensures that files are not already present in the destination.  if there's already a file with the same name, it checks that the md5 sum of the files are identical.  if they are not, it logs a message.

-The command will scan the host to find the NUMA nodes, and all the PCI devices, and map the PCI devices back to the NUMA node.
-
-It also provides a way to see the list of CPUs attached to the node.
-
-* Limitations
-** Device class
-For now only the following classes of hardware are cared for:
-- NVMe
-- network
-- GPU
