A simple program that helps to install fonts from:
$ pip install font-installer
$ font-installer -h
$ pip install git+https://github.com/ineshbose/font-installer.git
Installing fonts is as easy as browsing on sites, copying the URL, and using
$ font-installer <url>
$ font-installer https://www.dafont.com/bebas-neue.font # example
It is important that you use Run as Administrator (Windows) or sudo (Linux) to install. Simply paste the URL of your font and it just works!
No need to download the .zip to a directory, extract, install each file manually and delete the downloaded file!
