Corrected the parsing for assignment left-hand-side to allow for

whitespace inside the array declaration, as was (correctly) done
for pin connections.  Previously, "assign x[ 0] = 1'b1" would
fail due to "x[" being parsed as a token by itself.  Now, upon
reading an array opening bracket delimiter, the verilog parser
will continue to read tokens until it finds the closing bracket,
as it does for pin connections.

 BUILDING NETGEN:
 ----------------
-NETGEN version 1.4 uses the same "make" procedure as Magic version 7.5
+NETGEN version 1.5 uses the same "make" procedure as Magic version 8.1
 and IRSIM version 9.7:
 
    ./configure
    make
    make install
 
+Note: For FreeBSD, use 'gmake' instead.
+
+Note: On MacOS (Big Sur) follow the following procedure. If you have installed `xschem` and `magic` already on MacOS then steps (1) and (2) can likely be skipped.
+

+'''Michael Lange <klappnase (at) freakmail (dot) de>
+The ToolTip class provides a flexible tooltip widget for tkinter; it is based on IDLE's ToolTip
+module which unfortunately seems to be broken (at least the version I saw).
+INITIALIZATION OPTIONS:
+anchor :        where the text should be positioned inside the widget, must be on of "n", "s", "e", "w", "nw" and so on;
+                default is "center"
+bd :            borderwidth of the widget; default is 1 (NOTE: don't use "borderwidth" here)
+bg :            background color to use for the widget; default is "lightyellow" (NOTE: don't use "background")
+delay :         time in ms that it takes for the widget to appear on the screen when the mouse pointer has
+                entered the parent widget; default is 1500
+fg :            foreground (i.e. text) color to use; default is "black" (NOTE: don't use "foreground")
+follow_mouse :  if set to 1 the tooltip will follow the mouse pointer instead of being displayed
+                outside of the parent widget; this may be useful if you want to use tooltips for
+                large widgets like listboxes or canvases; default is 0
+font :          font to use for the widget; default is system specific
+justify :       how multiple lines of text will be aligned, must be "left", "right" or "center"; default is "left"
+padx :          extra space added to the left and right within the widget; default is 4
+pady :          extra space above and below the text; default is 2
+relief :        one of "flat", "ridge", "groove", "raised", "sunken" or "solid"; default is "solid"
+state :         must be "normal" or "disabled"; if set to "disabled" the tooltip will not appear; default is "normal"
+text :          the text that is displayed inside the widget
+textvariable :  if set to an instance of tkinter.StringVar() the variable's value will be used as text for the widget
+width :         width of the widget; the default is 0, which means that "wraplength" will be used to limit the widgets width
+wraplength :    limits the number of characters in each line; default is 150
+
+WIDGET METHODS:
+configure(**opts) : change one or more of the widget's options as described above; the changes will take effect the
+                    next time the tooltip shows up; NOTE: follow_mouse cannot be changed after widget initialization
+
+Other widget methods that might be useful if you want to subclass ToolTip:
+enter() :           callback when the mouse pointer enters the parent widget
+leave() :           called when the mouse pointer leaves the parent widget
+motion() :          is called when the mouse pointer moves inside the parent widget if follow_mouse is set to 1 and the
+                    tooltip has shown up to continually update the coordinates of the tooltip window
+coords() :          calculates the screen coordinates of the tooltip window
+create_contents() : creates the contents of the tooltip window (by default a tkinter.Label)
