# Usage: Just run in your svn directory. It will fire up your favourite
# $EDITOR and lets you edit the list of files unknown to subversion.
# Erase those that you don't want to ignore, and add wildcard patterns at
# will. When you close the editor, the files left in the list will be added
# as svn:ignore properties to their directories, amending the present list
# of svn:ignores.
