 dh_installman is a debhelper program that handles installing
 man pages into the correct locations in package build directories. You tell
 it what man pages go in your packages, and it figures out where to

+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.

 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
