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

[Adams, Russell L.]

I use my editfiles functions (ReplacementEdit and BlockEdit) for
exactly this.

I have an editfiles statement that rewrites the entire file
(ReplacementEdit) if a new version is present, and then multiple
BlockEdits that see if their block is current or missing and adds them
if thats the case.

Then of course I trigger a restart if the file was edited.

See:

http://cfwiki.org/cfwiki/index.php/Editfiles_Examples
http://cfwiki.org/cfwiki/index.php/Managing_Blocks_of_Code_with_Editfiles

I've m4 macroed these and the version numbering, so if I update the m4
file the version number is updated which forces the file to be
rewritten entirely, and defines additional classes for me to trigger
events with.

I could provide some code examples, etc, if you like.
