+.It Em LIBRARY
+The name of the library containing the documented material, which is
+assumed to be a function in a section 2 or 3 manual.  The syntax for
+this is as follows:
+.Bd -literal -offset indent
+\&.Lb libarm
+.Ed
+.Pp
+See
+.Sx \&Lb
+for details.
+.
+.It Em SYNOPSIS
+Documents the utility invocation syntax, function call syntax, or device
+configuration. 
+.Pp
+For the first, utilities (sections 1, 6, and 8), this is
+generally structured as follows:
+.Bd -literal -offset indent
+\&.Nm foo
+\&.Op Fl v
+\&.Op Fl o Ar file
+\&.Op Ar
+\&.Nm bar
+\&.Op Fl v
+\&.Op Fl o Ar file

+\&.In header.h
+\&.Ft "char *"
+\&.Fn foo "const char *src"
+\&.Ft "char *"
+\&.Fn bar "const char *src"

+\&.Cd \*qit* at isa? port 0x2e\*q
+\&.Cd \*qit* at isa? port 0x4e\*q
+.Ed
+.Pp
+Manuals not in these sections generally don't need a 
+.Em SYNOPSIS .
+.
+.It Em DESCRIPTION
+This expands upon the brief, one-line description in 
+.Em NAME .
+It usually contains a break-down of the options (if documenting a
+command), such as:
+.Bd -literal -offset indent
+The arguments are as follows:
+\&.Bl \-tag \-width Ds
+\&.It Fl v
+Print verbose information.
+\&.El
+.Ed
+Manuals not documenting a command won't include the above fragment.
+.
+.It Em IMPLEMENTATION NOTES
+Implementation-specific notes should be kept here.  This is useful when
+implementing standard functions that may have side effects or notable
+algorithmic implications.
+.
+.It Em EXIT STATUS
+Command exit status for section 1, 6, and 8 manuals.  This section is
+the dual of
+.Em RETURN VALUES ,
+which is used for functions.  Historically, this information was
+described in
+.Em DIAGNOSTICS ,
+a practise that is now discouraged.
+.Pp
+See
+.Sx \&Ex .
+.
+.It Em RETURN VALUES
+This section is the dual of
+.Em EXIT STATUS ,
+which is used for commands.  It documents the return values of functions
+in sections 2, 3, and 9.
+.Pp
+See
+.Sx \&Rv .
+.
+.It Em ENVIRONMENT
+Documents any usages of environment variables, e.g.,
+.Xr environ 7 .
+.Pp
+See
+.Sx \&Ev .
+.
+.It Em FILES
+Documents files used.  It's helpful to document both the file and a
+short description of how the file is used (created, modified, etc.).
+.Pp
+See
+.Sx \&Pa .
+.
+.It Em EXAMPLES
+Example usages.  This often contains snippets of well-formed,
+well-tested invocations.  Make doubly sure that your examples work
+properly!
+.
+.It Em DIAGNOSTICS
+Documents error conditions.  This is most useful in section 4 manuals.
+Historically, this section was used in place of
+.Em EXIT STATUS
+for manuals in sections 1, 6, and 8; however, this practise is
+discouraged.
+.Pp
+See
+.Sx \&Bl No \-diag .
+.
+.It Em ERRORS
+Documents error handling in sections 2, 3, and 9.
+.Pp
+See
+.Sx \&Er .
+.
+.It Em SEE ALSO
+References other manuals with related topics.  This section should exist
+for most manuals.  Cross-references should conventionally be ordered
+first by section, then alphabetically.
+.Pp
+See
+.Sx \&Xr .
+.
+.It Em STANDARDS
+References any standards implemented or used.  If not adhering to any
+standards, the
+.Em HISTORY
+section should be used instead.
+.Pp
+See
+.Sx \&St .
+.
+.It Em HISTORY
+The history of any manual without a
+.Em STANDARDS
+section should be described in this section.
+.
+.It Em AUTHORS
+Credits to authors, if applicable, should appear in this section.
+Authors should generally be noted by both name and an e-mail address.
+.Pp
+See
+.Sx \&An .
+.
+.It Em CAVEATS
+Explanations of common misuses and misunderstandings should be explained
+in this section.
+.
+.It Em BUGS
+Extant bugs should be described in this section.
+.
+.It Em SECURITY CONSIDERATIONS
+Documents any security precautions that operators should consider.
