[reportlab-users] simpler simple code for docs

[Carl Karsten]

docs section 3.3

... code as simple as this:

         class FontNameNotFoundError(Exception):
              pass
         def findFontName(path):
              "Extract a font name from an AFM file."
              f = open(path)
              found = 0
              while not found:
                   line = f.readline()[:-1]
                   if not found and line[:16] == 'StartCharMetrics':
                       raise FontNameNotFoundError, path
                   if line[:8] == 'FontName':
                       fontName = line[9:]
                       found = 1
              return fontName

This can be replaced with:

from reportlab.pdfbase import pdfmetrics
(topLevel, glyphData) = pdfmetrics.parseAFMFile(path)
fontName=topLevel['FontName']

I would post this to the issue tracker, but i cant log in and I wanted to get 
this posted somewhere.
