The Build Engine is a library that can be used to map a complex build process into a structured set of value objects.
This library is part of the php-ext.com portal.

Steps are the basic building blocks of a build and are self-contained, with a single purpose and a single responsibility.
A step can be as simple as changing the current working directory or as complex as cloning a repository or downloading a remote file.
Steps are defined in terms of commands *****
Stages are a more sophisticated block of a build, created by the combination of multiple steps, with a target goal.
A stage can be, for instance, build a library from its source code.
Note that a stage requires each step to be successful before executing the next step in the stage's step chain.
Pipelines are a full-blown build, composed by one or more stages.
A pipeline can be, for instance, download operating system dependencies required to build a library from its source code and then build it.
Note that a pipeline requires each stage to be successful before executing the next stage in the pipeline.
