+% TeX doesn't seem to support nested loops; therefore, this needs to be
+% flattened out to a single loop that runs from 0 to 330, where 331
+% is the total number of characters if you add the length of all the
+% lines together. This was determined by the following python code:
+%
+% >>> lines = [" " * abs(n) + "*" * (21 - 2 * abs(n)) for n in range(-10,11)]
+% >>> sum(len(line) for line in lines)
+% 331
+%
+% The general algorithm is as follows (prototyped in python):
+%
+%   linecounter = -10
+%   linelen = 0
+%   for charcounter = 0 to 330:
+%       # If start of line, reset all variables
+%       if linelen < 1:
+%           line = ""
+%           numspaces = abs(linecounter)
+%           numstars = 21 - 2 *numspaces
+%           linelen = numspaces + numstars
+%       # If not done with spaces, append space to line
+%       if linelen > numstars:
+%           line += " "
+%       # Else, append star to line
+%       else:
+%           line += "*"
+%       # If end of line, output line and increment line counter
+%       linelen -= 1
+%       if linelen < 1:
+%           print(line)
+%           linecounter += 1
