Z:gnu-man-db-manpages--bdf7f4-Once a manual page has been lo/en

Once a manual page has been located, a check is performed to find out if a relative preformatted `cat' file already exists and is newer than the nroff file. If it does and is, this preformatted file is (usually) decompressed and then displayed, via use of a pager. The pager can be specified in a number of ways, or else will fall back to a default is used (see option B<-P> for details). If no cat is found or is older than the nroff file, the nroff is filtered through various programs and is shown immediately.
