Buildout is a project designed to solve 2 problems:
Application-centric assembly and deployment
Assembly runs the gamut from stitching together libraries to create a running program, to production deployment configuration of applications, and associated systems and tools (e.g. run-control scripts, cron jobs, logs, service registration, etc.).
Buildout might be confused with build tools like make or ant, but it is a little higher level and might invoke systems like make or ant to get its work done.
Buildout might be confused with systems like puppet or chef, but it is more application focused. Systems like puppet or chef might use buildout to get their work done.
Buildout is also somewhat Python-centric, even though it can be used to assemble and deploy non-python applications. It has some special features for assembling Python programs. It’s scripted with Python, unlike, say puppet or chef, which are scripted with Ruby.
Repeatable assembly of programs from Python software distributions
Buildout puts great effort toward making program assembly a highly repeatable process, whether in a very open-ended development mode, where dependency versions aren’t locked down, or in a deployment environment where dependency versions are fully specified. You should be able to check buildout into a VCS and later check it out. Two checkouts built at the same time in the same environment should always give the same result, regardless of their history. Among other things, after a buildout, all dependencies should be at the most recent version consistent with any version specifications expressed in the buildout.
Buildout supports applications consisting of multiple programs, with different programs in an application free to use different versions of Python distributions. This is in contrast with a Python installation (real or virtual), where, for any given distribution, there can only be one installed.

There are a number of ways to install buildout. You can install it as you would any other package, using pip or easy_install. In this case, you’ll get a buildout command that you can use to build projects. To build a project, just use:
from a project directory.
Buildout’s (stubborn) philosophy, however, is that projects should be self-contained, and not require changes to a shared Python installation. To avoid changing a shared Python installation you can download a bootstrap script that, when run, will install buildout locally in your project.
The bootstrap script for buildout version 2 is at:
So, for example, to install buildout 2 in a project, you might:
wget https://bootstrap.pypa.io/bootstrap-buildout.py python bootstrap-buildout.py
Then to build your project, you can just run:
from the project directory.
buildout 2 is somewhat backward-incompatible with version 1. Most projects will probably work fine with either. If you need to keep using version 1, however, specify a version requirement when you use pip or easy_install, or use the version 1 bootstrap script at:
