As per man(7):
The only mandatory heading is NAME, which should
be the first section and be followed on the next
line by a one-line description of the program:
.SH NAME
item \- description
It is extremely important that this format is followed,
and that there is a backslash before the single dash
which follows the item name. This syntax is used by the
mandb(8) program to create a database of short
descriptions for the whatis(1) and apropos(1) commands.
Furthermore (lexgrog(1)):
When using the traditional man macro set, a correct NAME
section looks something like this:
.SH NAME
foo \- program to do something
Some manual pagers require the ‘\-’ to be exactly as shown;
mandb is more tolerant, but for compatibility with other
systems it is nevertheless a good idea to retain the
backslash.
