I have bolluxed the relationship between this repository (https://sourceforge.net/p/protdraw/code/HEAD/tree/) and my working copy. I think this occurred while I was making changes to the working copy directory structure using various unix commands as opposed to svn commands (I am new to svn). Once I started having trouble I probably ran one or more svn commands incorrectly in my attempts to recover.
I would like to just start over! The new directory structure I have in mind is different enough from the original one that this will be easiest for me. I have been searching the web for methods on how to do this, but I have not found a one that inspires me with much confidence. Could you please direct me to a resource on how to reset (start over) an svn repository? Please let me know if you need additional information.
