r3332@localhost: bruno | 2009-08-07 23:59:34 +0200

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
