How to install a downloaded Ruby gem file?

Question

How does \"gem install\" works ? It is not intuitive...

My gem is really here :

[root@localhost Téléchargement]# ll *.gem
-rw-rw-r-- 1 jean jean 16353818

Just some more clarification in case you need to build / install your own gem file in this example foo-bar.

gem build foo-bar.gemspec
gem install --local foo-bar-0.1.0.gem

I was researching how to do this and this post was first result :)
