I'm trying to decide whether or not to use 'require' or 'do' in my scripts, to make maintenance easier.

At the moment I have 3 portions of a script that create each page. The first and last portions are the same for all pages, and the middle one is unique for all pages.

I'm trying to decide whether or not to make the first and last one into another file and use require or do, and call them as subroutines (so that I only have to modify 1 file, to affect all pages for the 1st and last half of the page) or if I should just leave it all in each file, and just have a lot more maintenance (having to modify every file, rather then just one) if I want to change something.

ie.
--- part 1 ---
--- part 2 ---
--- part 3 ---
for every single file.
vs.
--- require file 2 --- (OR the 'do' parts in the following)
--- 'do' part 1 --- (from file 2)
--- part 2 ---
--- 'do' part 3 --- (from file 2)


Basically, my questions are:
- How demanding would running two 'do' or one 'require' in a script be, vs. none at all? Is this somethign that could potentically create a tremendous strain on a server? - What's the performance difference between 'do' and 'require'?

Just trying to do this right the first time, rather then having to recode it down the road because I didn't take the time to do it properly this time :-)

Any feedback is greatly appreciated!
