-# You should use the equivalent packages for your distribution if you are not using a Debian-like distribution of GNU/Linux.
-sudo apt install perl make libwww-perl liburi-encode-perl libjson-perl liblwp-protocol-https-perl libtest-mockobject-perl libtest-most-perl libmojolicious-perl
-perl Makefile.PL
