Default system browser

Debian FAQs explain how to manage many packages that provide different versions of a program, both of which provide the same core functionality. Today I learnt how to use update-alternatives to choose Swiftfox as my default system browser.
I installed Swiftfox in /usr/local/swiftfox, so here it is: 

update-alternatives --install /usr/bin/x-www-browser x-www-browser /usr/local/swiftfox/swiftfox 90
update-alternatives --config x-www-browser

Do it as root. You can replace the value "90" with a most appropriate value.
