  • bkpinfo->tmpchdir is now dynamically allocated
  • reorganize how tmpdir and scratchdir are initialized and the startup of the main sections
  • change of interface for maintain_collection_of_recent_archives, mondo_makefilelist, chop_filelist
  • sensibly_set_tmpdir_and_scratchdir => sensibly_set_scratchdir
  • reset_bkpinfo => init_bkpinfo
  • add function mr_free_bkpinfo
  • Fix a bug in mr_strtok
  • mondoarchive seems to globally work. Newt stuff needs more testing
  • Property svn:keywords set to Id
