Z:englobe-dpkg-man--7f11eb-You may specify a perl regular/hu

You may specify a perl regular expression to match files you want filtered out of the list of files for the diff. (This list is generated by a find command.) B<-i> by itself enables the option, with a default that will filter out control files and directories of the most common revision control systems, backup and swap files and Libtool build output directories. There can only be one active regexp, of multiple -i options only the last one will take effect.
