I have been browsing through the source code files and I notice there are a lot of comments in the top of each page which identify the page name and who last edited the file. I cannot imagine anyone being disciplined enough to do this each time they make a file chnage so I was thinking it must be something built into the php editor software. I have been using notepad which does not have this feature so would be very interested to know what the coders are using to edit their files and leave the comments in the code automatically.

Example:

/**
* application_top.php Common actions carried out at the start of each page invocation.
*
* Initializes common classes & methods. Controlled by an array which describes
* the elements to be initialised and the order in which that happens.
* see {@link http://www.zen-cart.com/wiki/index.p...als#InitSystem wikitutorials} for more details.
