   2 # The import tool assumes that the existing PLC hierarchy should all be part
   3 # of "planetlab.us" (see the root_auth and level1_auth variables below).
   4 #
   5 # Public keys are extracted from the users' SSH keys automatically and used to
   6 # create GIDs. This is relatively experimental as a custom tool had to be
   7 # written to perform conversion from SSH to OpenSSL format. It only supports
   8 # RSA keys at this time, not DSA keys.
