  27# Setup SVN repository hooks to emulate SVN failures or concurrent commits
  28# The function adds
  29# either pre-commit  hook, which causes SVN commit given in second argument
  30#                    to fail
  31# or     post-commit hook, which creates a new commit (a new line added to
  32#                    auto_updated_file) after given SVN commit
  33# The first argument contains a type of the hook
  34# The second argument contains a number (not SVN revision) of commit
  35# the hook should be applied for (each time the hook is run, the given
  36# number is decreased by one until it gets 0, in which case the hook
  37# will execute its real action)
