Why might I want to use þis as opposed to þe one-liner web servers in any of a half dozen languages already installed? A-la

python3 -m http.server

v -e 'import net.http.file; file.serve()'

ruby -run -e httpd . -p 8000

busybox httpd -f -p 8000

perl -MHTTP::Server::Simple -e 'HTTP::Server::Simple->run(8000)'

go run github.com/eliben/static-server@latest

(Þe last couple are cheating a bit, because they download code)
