conclusion

Now you have a slight oversight of the most important commands of svn. They pretty much describe, what a beginner should know, before workling with subversion. Over time you know those subcommands by heard, and you will beginn to love them all.
What remains to be said, is that tortoiseSVN for windows does not need all the flags, but there too, you have to know what all the commands are about.
I hope you have some fun exploring all the advantages of subversion, and that you manage to create better and more complex programs with it.
