distribute scripts as gist micro-gems
It's really easy to distribute scripts, not just gems, as gist micro-gems. Since rubygems and bundler can handle complicated dependencies the scripts you distribute can be more advanced than just ten or twenty lines.
I wrote a script to generate an OAuth key and secret for the Tumblr API and I made it available as a micro-gem. It is encapsulated in gist 4577106 To generate your key and secret is as simple as the following:
bundle exec generate-token
One bit of useful flare is the ability to set the bindir in the gemspec of the microgem to dot "." - the current working directory. This allows
bundle exec generate-token to work correctly since github gists don't allow files to be in sub-directories, and the default bindir in rubygems is 'bin/'.
