+DESCRIPTION:
+Parse the command line for specific options
+
+HEADER:
+cmdline.h
+
+PARAMETERS:
+argc        - Value passed to program through argc variable
+argv        - Pointer to the argv array passed to the program
+format      - A string representing the expected format of the command line
+argument    - Pointer to optional argument on command line
+
+RETURNS:
+Character code representing the next option parsed from the command line by
+getcmdopt. Returns ALLDONE (-1) when there are no more parameters to be parsed
+on the command line, PARAMETER (-2) when the argument being parsed is a
+parameter and not an option switch and lastly INVALID (-3) if an error
+occured while parsing the command line.
+
+REMARKS:
+Function to parse the command line option switches in UNIX System V style.
+When getcmdopt is called, it returns the character code of the next valid
+option that is parsed from the command line as specified by the Format
+string. The format string should be in the following form:
+
+    "abcd:e:f:"
+
+where a,b and c represent single switch style options and the character
+code returned by getcmdopt is the only value returned. Also d, e and f
+represent options that expect arguments immediately after them on the
+command line. The argument that follows the option on the command line is
+returned via a reference in the pointer argument. Thus a valid command line
+for this format string might be:
+
+    myprogram -adlines -b -f format infile outfile
+
+where a and b will be returned as single character options with no argument,
+while d is returned with the argument lines and f is returned with the
+argument format.
+
+When getcmdopt returns with PARAMETER (we attempted to parse a paramter, not
+an option), the global variable NextArgv will hold an index in the argv
+array to the argument on the command line AFTER the options, ie in the
+above example the string 'infile'. If the parameter is successfully used,
+NextArgv should be incremented and getcmdopt can be called again to parse any
+more options. Thus you can also have options interspersed throught the
+command line. eg:
+
+    myprogram -adlines infile -b outfile -f format
+
+can be made to be a valid form of the above command line.

+REMARKS:
+Function to parse the command line according to a table of options. This

+to parse each option into a variable of the specified type. The routine
+can parse integers and long integers in either decimal, octal, hexadecimal
+notation, unsigned integers and unsigned longs, strings and option switches.
+Option switches are simply boolean variables that get turned on if the
+switch was parsed.
+
+Parameters are extracted from the command line by calling a user supplied
+routine do_param() to handle each parameter as it is encountered. The
+routine do_param() should accept a pointer to the parameter on the command
+line and an integer representing how many parameters have been encountered
+(ie: 1 if this is the first parameter, 10 if it is the 10th etc), and return
+ALLDONE upon successfully parsing it or INVALID if the parameter was invalid.
+
+We return either ALLDONE if all the options were successfully parsed,
+INVALID if an invalid option was encountered or HELP if any of -h, -H or
+-? were present on the command line.
