I want to install a plugin created for rails called ‘attachment_fu’ .
However, I am not sure how to do this. I searched the ‘rails/plugin’
console menu but I could not find the plugin listed. Can an install
any plugin that is not listed in this menu or should I use the console
‘script/plugin install http://svn.techno-weenie.net/projects/plugins/attachment_fu/’
to install it.
