+ CHANGELOG:
+Thu Feb 25 2001 Andrej Borsenkow <Andrej.Borsenkow@mow.siemens.ru>
+- added ``--'' as delimiter for supermount fs options to avoid mount errors on fs-specific options
+- added --mountpoint option to operate on single mount point
+- changed condition to enable supermount to (($fs eq iso9660) || (($fs =~ m/$fs_ok) &&
+ ($dev =~ /^\/dev\/($dev_ok)$/))) && ($opt =~ m/(^|.*,)user.*/ ) 
+Before it tried to supermount Windows vfat partitions that were defined with user option.
+
+Thu Apr 13 2000 Denis Havlik <denis@mandriva.com>
+- moved definitions of "good" and "bad" fs-options, "allowed fs-s" and "good devices" to top of the script for easier maintainance.
+-  added &clean_options(\@opt,\@must, \@bad) function, which parses the @opt
+  array, adds the "must" options and removes the "bad" ones, and re-wrote the 
+  while (<FH>) {} loop to take advantage of this functions.
+- simplified the fstab parsing (split instead of regexp-s)
+- changed the rules used to decide which mount points are going to be 
+supermounted to: ($fs eq "iso9660") || (( $fs =~ m/$fs_ok/ ) &&
+ (($dev =~ /^\/dev\/($dev_ok)$/) || ($opt =~ m/(^|.*,)user.*/ )) )
