Presented here are two modules, "html_help" & "Zam". Both modules contain two classes.
"html_help" contains "html_table" and "html_month". A html_table produces tables with a readable format. A html_month is just a logical extention of the html_table.
"Zam" contains "array" and "matrix". An array is 1D list with fixed sized and mutable internals. A matrix is the same except for the fact that it is 2D.

Note: the DST bug should be fixed now.
