= Analytical Engine

The Analytical Engine (`ae`) is a Ada dependency management tool intended to
make working with Ada project dependencies easier.


== schematics.yaml

[source,yaml]
----
catalogs:
  - builtin://berriedale
  - file:///tmp/ae-catalog
schematics:
  - adacore/gtkada
----

The `schematics` key is of vital importance as that declares the dependencies
for this project. The format is `publisher`/`name` and will map to a directory
structure in the `catalog` wherever it may be found.


== `ae` tool

=== Installing schematics

[source, bash]
----
% ae install
----

The subcommand `install` will populate `$PWD/.ae` with the schematics defined
in the `$PWD/schematics.yaml` file.


=== Using dependencies

The subcommand `run` can be used to provide the appropriate environment
variables for executing a program such that it can access installed schematics.

[source, bash]
----
% ae run gprbuild
----


== .aerc

The .aerc should be added to specific projects to override user-specific
settings. Generally speaking these files should never be checked in.
