Almost all man pages are affected by the following problem (detected by Lintian):

manpage-has-bad-whatis-entry

Each manual page should start with a "NAME" section, which lists the 
    name and a brief description of the page separated by "\-". The "NAME" 
    section is parsed by lexgrog and used to generate a database that's 
    queried by commands like apropos and whatis. This tag indicates that 
    lexgrog was unable to parse the NAME section of this manual page.

For manual pages that document multiple programs, functions, files, or 
    other things, the part before "\-" should list each separated by a comma 
    and a space. Each thing listed must not contain spaces; a man page for a 
    two-part command like "fs listacl" must use something like "fs_listacl" 
    in the "NAME" section so that it can be parsed by lexgrog.

Refer to the lexgrog(1) manual page, the groff_man(7) manual page, and 
    the groff_mdoc(7) manual page for details.
