An AURA project is, specifically, any distinct Ada program library 1 that contains the AURA subsystem (the package AURA and its children). This includes contexts where the implementation automatically generates one.
In laymen’s terms, a project is the codebase of a program, and optionally the repository-sourced AURA subsystem dependencies. Recall that a program in the Ada sense can be more than one executable (partition) 2. Similarly, an AURA project can produce multiple partitions in a single codebase.
The reference implementation (AURA CLI), further defines a project as any directory on the file system that either contains the AURA subsystem packages, or is the current directory when the AURA CLI tool is run.
AURA CLI will auto-generate the basic AURA subsystem packages in the current directory if they are not found.
The Ada Reference Manual defines a program library as follows: “An implementation may support a concept of a program library (or simply, a “library”), which contains library_items and their subunits. Library units may be organized into a hierarchy of children, grandchildren, and so on.”
The Ada Reference Manual defines a program as follows: “A program is a set of partitions, each of which may execute in a separate address space, possibly on a separate computer. “
