When creating a public GitHub repo, what's the best way to deal with 3rd party libs?

Should I include 3rd party libs in my public repo, or just add them as a requireme开发者_如何转开发nt in a readme?

Is it a library stored in git and you are tracking an unstable or development tree? Use git submodule.

If the library is not stored in git, but you are tracking an unstable tool, write a small shell script to automate your life of fetching the required source.

Is it a released library? Require the user to provide it.
