A Macro is a special token that Epsilon expands at run time. Macros can occur in scripts, templates, and command line arguments, and in the subject line, body, or address of an email.
You can enter a macro in any place where you can enter text. Macros can be created in the following format:
@@<macro_name>@@
For example:
@@BACKUP@@
Macros are used to make scripts generic, and form the basis for creating reusable workflows.
