Single-user source control?
delphi, version-control
Solution
SVN will be more than enough as you'll mostly use it for backing up and diff'ing versions.
You can use VisualSVN Server and TortoiseSVN with Delphi IDE Integration. All of these are freeware. If you wish to use any other freeware SCM with Delphi IDE integration you'll need to buy SourceConneXion or Athlant. Also, if you're using D2009 you'll need to convert strings to ansistrings in order to get TortoiseSVN addon for delphi to work.
Problem
Searching with '[Delphi] "source control"' didn't return much, so here goes: For those of you Delphi programmers working on your own, what source control do you like? I know about TortoiseSVN (which can be used without a server), but I'd like to know if there are better options before choosing it. Thank you.
