** stoptions.h
**
** Abstract the spacetrace options into a reusable format, such that
** many different pieces of the code can utilize the common list.
*/
/*
** There are three types of options.
** The destinction is quite important.
**
** CMD options are accessible from only the comamnd line.
** Such options should be considered global/static for the entire
** run of the application.
** Once set, no one can change these options during the run.
**
** WEB options are accessible from the web server options page.
** Such options can and will be changed on a per user basis during
** the run of the application.
** You should NEVER make an option a WEB only option, as this will
** break batch mode processing, and will likely not correctly
** define the options structure itself.
** These options will control the data caching used in the application
** to match a client to a cache of data.
**
** ALL options are both CMD and WEB options, with the properties of WEB
** options (the user will change these on a per client basis).
** Most likely this is the type of option you will desire to create.
*/
/*
** All types of options have some combination of the following elements:
**
** option_name The name of the option.
** option_genre Area the option effects; STOptionGenre.
** default_value The default value for the option.
** array_size Used to size a string array.
** multiplier Some numbers prefer conversion.
** option_help Help text to explain the option.
**
** NOTE! that the multiplier should be applied to the default value if you
** are going to assign the default_value into anything.
**
** Be very aware that adding things to a particular genre, or adding a genre,
** may completely screw up the caching algorithms of SpaceTrace.
** See contextLookup() or ask someone that knows if you are in doubt.
**
** The actual definition of the WEB and CMD macros however is left to the
** end user.
** We cover those that you do not define herein.
