[Resolved] Concurrant-Version-Somthing

[Megahertza]

At the moment I'm learning php and building a site. After do alot of work on some code I ussally forget what I was working on the next day and I end up looking through lines of code looking for uncompleated code or different code. Does anyone have a program where i can make entries detailing work done and dates compleated and so on. I believe there called Cvs (Concurrant-Version-Somthing) I need a simple 1 siuted for a website. I'd be happy for any help

CVS: cvshome.org
or
Subversion: subversion.tigris.org

EDIT:
but these are version control systems, not quite what you are looking for.

Put detailed comments above every class and function, plus smaller comments above lines which might cause confusion later. When done properly you can even generate documentation at the end, based on the comments.
