I did it like this in a custom Zope 2 site:

# Print the first paragraph or the first `maxchars' characters,
# whichever is shorter.

text=context.text
maxchars=1000
i=0
while i < maxchars and i < len(text):
    if text[i:i+2]=='\n\n':
        print text[:i]
        break
    i=i+1
if i == maxchars:
    print text[:maxchars] + "..."
else:
    if i == len(text):
        print text
return printed
