  * Removed one level of indirection in the command-line options parsing.
  Before, getOpt would return a list of Flag, which had a one-to-one correspondence with functions TempFlags -> TempFlags. This made it uneccessarily difficult and error-prone to add new flags. I removed the Flag type and replaced the values with TempFlags -> TempFlags functions. This should have the side effect of making the tar path flag work, since it was not interpreted before.
