+install them based on the section field in their .TH line. If you have a
+properly formatted .TH line, your man page will be installed into the right
+directory, with the right name (this includes proper handling of pages
+with a subsection, like "3perl", which are placed in man3, and given an
+extension of ".3perl"). If your .TH line is incorrect or missing, the program
+may guess wrong based on the file extension.
+
+It also supports translated man pages, by looking for extensions
+like .ll.8 and .ll_LL.8, or by use of the --language switch.
+
+If dh_installman seems to install a man page into the wrong section or with
+the wrong extension, this is because the man page has the wrong section
+listed in its .TH line. Edit the man page and correct the section, and
+dh_installman will follow suit. See to L<man(7)> for details about the .TH
+section. If dh_installman seems to install a man page into a directory
+like /usr/share/man/pl/man1/, that is because your program has a
+name like "foo.pl", and dh_installman assumes that means it is translated
+into Polish. Use --language=C to avoid this.
