-# Import PLC records into the SFA database. It is indended that this tool be
-# run once to create SFA records that reflect the current state of the
-# planetlab database.
-#
-# The import tool assumes that the existing PLC hierarchy should all be part
-# of "planetlab.us" (see the root_auth and level1_auth variables below).
-#
-# Public keys are extracted from the users' SSH keys automatically and used to
-# create GIDs. This is relatively experimental as a custom tool had to be
-# written to perform conversion from SSH to OpenSSL format. It only supports
-# RSA keys at this time, not DSA keys.
