Finding sphinx-build

Sphinx is an excellent tool for generating documentation for projects implemented in Python. Note that after installing Sphinx, the which command won't show you the location on the package interface directly:

   which Sphinx

What you're looking for instead is the sphinx-build executable:

   which sphinx-build
   /usr/local/bin/sphinx-build

And it is the sphinx-build executable that you can query for help when starting and stopping the system:

   which sphinx-build --help

And so on.
