A few helper scripts that I use for development with Jekyll. You can include these as a submodule in your Jekyll git repo like
$ git submodule add git@github.com:erikw/jekyll-utility-scripts.git bin/
$ bin/serve.sh # for examplediff-upstream-theme.sh: Open up a vim multi-tab diff of all files that you've overriden from an upstream theme.jekyll.sh: Wrapper to run jekyll commands.serve.sh: Convenient script for local development making short options for controlling the jekyll build process.
