title: Recursively ignoring files in the entire source tree in subversion
body: <p>I am not new to Subversion, but I have up till now used Tortoise and never the commadn line.  My question is, how do I ignore all files like *.o from the ENTIRE source not just the root.</p>
  
  <p>For example, if I have the following files:
  /myfile.o
  /folder1/myfile2.o
  /folder1/folder1.1/myfile3.o
  /folder2/myfile4.o</p>
  
  <p>If svn propedit svn:ignore "." in the root directory, and add *.o, it will ignore the myfile.o, but does not ignore /folder1/myfile2.o, /folder1/folder1.1/myfile3.o, /folder2/myfile4.o.  Is there a way to add *.o in for an entire project (I cannot do it for the entire repository, which I know can be done, because this project is in a repository with many other projects)?</p>
  
  <p>Please let me know if I need to clarify.  Thanks!</p>
