-- Learning scripts/module
 -- $self->{LOG} goes to module log.pm
     -- require "structured" replacement for debug messages and
        other STDOUT warning print statements
-- code can always be improved...
Can we monitor all activity, not just poll it?
 -- write a sig-list-file generator script (e.g., watches for 24 hours and
    then writes a file which can be hand-modified afterwards);
 -- improve sigs:  e.g., look at cwd or .so files used, or...
 -- write a sig-list-file generator script (e.g., watches for 24 hours and
    then writes a file which can be hand-modified afterwards);
 -- move sig list to a file;
 -- write a sig-list-file generator script (e.g., watches for 24 hours and
    then writes a file which can be hand-modified afterwards);
     -- or: two files:  one for std Solaris 7 (or other std OS),
                        one for local stuff, e.g., nqs, this latter generated
                            by the script;
     -- should be able to compare any two sets of logs (check it can do
        this and _document_ this --- its upto Scripts/taillog to get
        the "second" set of log files by some means, e.g., this could
        be scp from user machine to sylo machine (with cheesewire
        running on sylo machine)
 -- use inotify:
        http://www-128.ibm.com/developerworks/linux/library/l-inotify.html
 -- if a change occurs, check if its its from dpkg or rpm (or whatever),
    if it is log and update sig, if not then usual warning
 -- adaption:  if new files appear in a configured directory should be
    incorporated automatically;
 -- addition to a file, no decrease, e.g. for wtmp and log files (how to
    deal with log-rotate --- or write a dedicated log-watch util (log files
    should never _decrease_ in size, only be manipulated by log-rotate);
---------------------------------------
DONE
 -- add in directory listings :  are there any new files in said directory? 
 -- different time scales :
     -- important files each hour;
     -- more files each night;
