  The BlackBox gives you a way to have /two/ revisions of your program
  (the "server" configuration, as described by Fyodor), i.e. the
  "server" copy and the "client" copy. The contents of the "client"
  override the corresponding files of the "server". This is a very
  useful feature for BlackBox core development, and it can be used to
  some extent in your application projects, but if you are used to
  thinking about revision control systems as of "time-machines" for
  your code, then no, that does not work that way.

  I use Subversion for all my software projects, including BlackBox,
  even though I don't need the access control features (the
  repositories are local folders on my machine). The biggest advantage
  for me since I started using a revision control system was the
  change of mind that makes you see the development process not as a
  flow of "work" in a general direction, but as a series of
  incremental changes, each with explicitly stated meaning and
  purpose.

  When you don't just create something for yourself, but deploy your
  software product to a customer, you will some times get reports of
  erratic behaviour of your product. At the time of the report you've
  probably moved on with your project since the version you deployed.
  You could easily get trapped in a situation when:
  1) the fix is trivial and can be done instantly to make the customer
  happy;
  2) your current source code is in the middle of a big rework that
  can't be finished in a timely fashion.
  This is no issue for you if you know exactly which revision of the
  source code was used to build the customer's version of the program.
  You just get the older code, make the fix, and continue with your
  big rework (you'll find description of the best approach to version
  branches on the 'Net, probably even in the Subversion book).

  Another reason for using a revision control system is, of course,
  development branches. I've got a branch for my own experiments, a
  branch for trying out the Component Pascal Collection, a branch for
  School BlackBox, which I used to be involved with, and some
  application programs. All those share a considerable amount of code.
  When I make a change to a common module, I can port the change
  across to all the interested branches without much hassle. Plus, the
  Subversion repository makes a great backup tool, since all the
  shared code is actually stored only once (and packed).

  The best practices for using Subverion are described here:
  http://svn.collab.net/repos/svn/trunk/doc/user/svn-best-practices.html
  Those are applicable to any project.

  In addition to that, my approach is as follows.
  \ProjectOne\trunk
  \ProjectOne\tags
  \ProjectOne\branches
  \ProjectTwo\trunk
  \ProjectTwo\tags
  \ProjectTwo\branches
  ...

  I use one big repository for all of my BlackBox-related work. I use
  the "server" configuration, where I keep the BlackBox distribution
  intact. All of my projects are in their own folders, being "clients"
  for the "server". This way
  1) BlackBox folders don't get in the way;
  2) I can locally override things for my project, while other
  projects use their own (or default) stuff.

  I only keep the source code and documentation in the repository (no
  binary or symbol files, with the exception of the BlackBox itself,
  which I imported fully). I keep empty "Code" and "Sym" folders in
  the repo, because I don't want BlackBox to ask me if I want to
  create them on compilation of a fresh checkout.

  There is sort of a master-file for every project. The file contains
  hyperlinks to all files of the project. The list of files is divided
  in categories: subsystem -> source, resources, etc.; files are sorted
  alphabetically in each category for quick search. The subsystem's
  prefix is omitted from the hyperlink label. The master-file also
  contains commanders for full compilation and unloading of all
  modules of the project, as well as running a test suite, if any.
  This is a mouse-clicking version of the "make" functionality. Come
  to think of it, it could be bound to a hotkey, but I didn't get that
  far before I quit working in BlackBox.

  (Sorry if this reply shows in the wrong place of the thread, but Google
  has this stupid "basic HTML" interface where I can't figure out how to
  reply to a specific e-mail. And their "standard" view shows nothing in
  my Opera 9.63. And BlackBox mailing list does not accept e-mails
  from my normal yandex e-mail with good interface.)
