Descriptions in this manual follow the UNIX Programmer's Manual format;
The text is collected into a set of subsections, which appear when
applicable:

The HEADING of each entry gives a very short description of the purpose
of the functions in that entry.

The NAME subsection lists the exact names of the header or subroutines
covered under the entry.

The SYNOPSIS summarizes the use of the function being described, including
required include statements, formats, and passed parameters.  A few
conventions are used:

	Boldface words are considered literals, and are typed just as
	they appear.

	Square brackets [ ] around an argument indicate that the argument
	is optional.  When an argument is given as 'name', it always refers
	to a file name.

	Ellipses '...' are used to show that the previous argument-prototype
	may be repeated.

	A final convention is used by the commands themselves. An argument
	beginning with a minus sign '-' is  often taken to mean some sort of
	option-specifying argument even if it appears in a position where a
	file name could appear. Therefore, it is unwise to have files whose
	names begin with '-'.

The DESCRIPTION subsection discusses in detail the subject at hand.

A RETURN VALUE subsection gives some specific information on the return
value and some general warning notes, if necessary.

A SEE ALSO subsection gives pointers to related information.

A DIAGNOSTICS subsection discusses the diagnostic indications which may
be produced. Messages which are intended to be self-explanatory are not
listed.

An EXAMPLE subsection gives a program example, usually in form of a
complete program fragment that illustrates the use of the functions.

The LIMITS section states some program limitations, if necessary.

The IDENTIFICATION section states the program name, version number,
author, date of release and short copyright statement.

The CHANGES section lists a log of program changes.

The LEGAL section (if necessary) states the license and disclaimers.

The BUGS subsection gives known bugs and sometimes deficiencies.
Occasionally the suggested fix is also described.
