Description

This lookup checks a list of files and paths and returns the full path to the first combination found.

As all lookups, when fed relative paths it will try use the current task's location first and go up the chain to the containing locations of role / play / include and so on.

The list of files has precedence over the paths searched. For example, A task in a role has a 'file1' in the play's relative path, this will be used, 'file2' in role's relative path will not.

Either a list of files C(_terms) or a key `files` with a list of files is required for this plugin to operate.
