2 | * | |
3 | * ptdump: Program to dump the AFS protection server database | |
4 | * into an ascii file. | |
5 | * | |
6 | * Assumptions: We *cheat* here and read the datafile directly, ie. | |
7 | * not going through the ubik distributed data manager. | |
8 | * therefore the database must be quiescent for the | |
9 | * output of this program to be valid. | |
