Resetting line count in dtx files

Question

I'm writing a dtx file containing several source files. Is there a way to reset the line counter when commenting the code of a different file?

My dtx file looks something like this:

....
%\iffalse
%<file1>
%\fi
% .... comments and code of file 1
%\iffalse
%</file1>
%<file2>
%\fi
% .... comments and code of file 2 ... etc.

and I would like the line numbers of the code of file2 to start with 1 again.

The doc package uses the CodelineNo counter so \setcounter{CodelineNo}{0} probably does what you need.
