 == Aliases
 
-When invoking commands in the context of a project, it is common to need to specify complex data that is hard to quote on the command line. As Clojure programmers, we strongly prefer to specify that data in Clojure syntax (http://edn-format.org/[edn]). The <<deps_edn#,deps.edn>> file format allows us to define arbitrary Clojure data and give that data a name using <<deps_edn#aliases,aliases>>. Aliases are simply keywords that name edn data.

 Each execution mode of the Clojure CLI has many configuration options (the "arg map"). These can be defined in edn maps via aliases and selected on the command line using the aliases in `-A`, `-X`, `-T`, or `-M`. Below is a list of all arg map keys - unless otherwise noted, these are valid in all execution modes.
