Ordinarily, Build installs the unformatted manual pages in a place such as /usr/share/man/man8, which is in the man* directories. Unless it is told not to, it will also install the formatted pages in a place such as /usr/share/man/cat8, which is in the cat* directories. If your site stores only unformatted pages (perhaps to save disk space), you can prevent the installation of the formatted pages by using an m4 declaration such as this:

define(`confDONT_INSTALL_CATMAN')
