file1.art

% We can insert code when adapting a file, based on the breakpoints in the file
% Matching of inserts to breakpoints happen by the break name.

#adapt: "file2.art"
	#insert "breakA"
        +++++++++++++++++++++++
              INSERT CODE
        +++++++++++++++++++++++
	#endinsert
#endadapt

file2.art

This is "file2.art" content START
#break "breakA"

This is "file2.art" content END
% Breaks can have default content
% If we insert in "BreakB" we will not see the default content of the breakpoint.
% We can use #insert-after and #insert-before commands if we want to keep the default content.
% Modify this code to see the outcome.
#break: "breakB"
	Default Content of "breakB"
#endbreak

file3.art

% Note: The insert command will insert in every occurance of the same breakname (can be multiple) along adapt-links.
%       The insert commands with the same name are getting concatenated along adapt-links.
