The sandbox plugin for rubygems helps you manage your command-line tools and their dependencies. Sandboxed gems are installed in their own private rubygem repositories with all of their dependencies. This means that you don't have to have a rat's nest of gems in your global repository in order to run popular command-tools like rdoc, flog, flay, rcov, etc. gem sandbox has the following sub-commands: * install gem_name ... - install 1 or more gems * plugin gem_name plugin_name ... - install a gem and plugins for it * remove gem_name ... - uninstall 1 or more gems * help - show this output Once you install gem sandbox will output something like: Copy the following scripts to any directory in your path to use them: cp /Users/USER/.gem/sandboxes/GEM/bin/TOOL _in_your_$PATH_ Copy the scripts to a directory in your path (eg ~/bin or /usr/bin) and you're good to go.
