Puppet users - Apr 2014 - Augeas lens to change an arbitrary line in a file?

Hi,

I'm new to Puppet, and also new to Augeas.

I want to change a line in a file. In particular, the file is
  /usr/share/ghostscript/${gs_version}/Resource/Init/gs_init.ps
and the line is
  % /DEFAULTPAPERSIZE (a4) def
that I want to change into
  /DEFAULTPAPERSIZE (a4) def

Is Augeas the right tool for such a task? I looked through its
available lenses, but there ain't no Postscript lens.

Of course, the other approach would be to use an exec resource to
change that line.

What is best practice?

	Joachim
