Re: editfiles template; multiple edits; setting a class on update

[Russell Adams]

You're absolutely correct. The trigger is the version number, which my
current macros use a timestamp which is written to the template when
the m4 file is converted to a cfengine file.

Because I use make to handle compiles, simply touching a m4 file will
trigger a rewrite of the file on the hosts after my configs are
recompiled.
