Mine is a bit longer but I have found it very useful
Please triple check it suits your purpose before use !
Absolutely no warranty !
Three vital lines that do all the work are commented out below
for the -os and -or options
# print `$command`;######################################!!!!!!!!
The -oc option is enabled
The script started out of a list of vital files I needed to save
and restore when upgrading my server. It just grew!
Hope it helps

#-os is used to save maui config files to a "safe" tar archive
#-or is used to restore maui config files from tar achive onto the same or a different machine
#-oc is used to compare existing config files on a machine with those in a maui "safe" tar archive
# The file list is that defined explicitly by a @list="..." statement or by the contents of a directory
# For the directory cases (/etc/samba, ...) the file list is dependent upon the option given
# For -os the list is defined by the files present in that directory on the machine
# For -or and -oc the file set is defined by the files present in the "safe" directory
