I've developed a site for a small to medium sized company. The current website is only 3 months old. After attaining much success, the company has plans to expand its site. This is great for the business, but is a bit of a pain for the web developer - myself.
All the pages I have created thus far use a consistent theme and layout with static XHTML pages. This means that if I make changes to the template on one page, I have to change all the rest of the *.html pages.
I was looking for some sort of command line application or a simple GUI application that I could utilize for creating templates for static xhtml pages. Furthermore, the application will allow me to update all the pages on the site that use the template. Do you guys have any recommendations? I'm preferrably looking for open-source solutions; I don't have much money.
