Please note that at this stage we are only examining use of the Webel '$opt$' help holders conventions in lower-level packages, which rely on "manual" naming conventions; in later slides we'll see how Webel extensions of MTools for OO such as the MOpt class can be used to encapsulate the help holders for the Webel options convention.

Notes

[NAMING, OPTION, PATTERN, TIP]{OPTION} Mathematica: Webel: You CAN/MAY use $ in variable names and function names - just not as the first character before a Capital - and it's extremely useful. You won't get sent to Azkaban prison if do you use a $ character!
