Z:gnu-man-db-manpages--0a1408-The manual pager utilities pac/en

The manual pager utilities packaged as B make extensive use of B database caches. These caches contain information such as where each manual page can be found on the filesystem and what its I (short one line description of the man page) contains, and allow B<%man%> to run faster than if it had to search the filesystem each time to find the appropriate manual page. If requested using the B<-u> option, B will ensure that the caches remain consistent, which can obviate the need to manually run software to update traditional I text databases.
