Setting up a new Subversion repository so that multiple users can work on the same files at the same time. I didn't document this carefully enough last time, so I'll go through this in detail:

• On the local machine, establish a file structure which contains only the files and directories you want to manage through SVN.
• At the command line, in that location, build the initial repo structure. In this case, I did this:
  • svn mkdir https://[path-to-repo]/trunk
  • svn mkdir https://[path-to-repo]/trunk/xml
• svn checkout https://[path-to-repo]/trunk/xml .
• Add all your files and folders to the tree, like this:

  svn stat | grep "^?" | awk '{print $2}' | xargs svn add
  

  This command is suggested and nicely explained by this article.
• svn commit
