thanks .. with a few minor fixes it works perfectly for my needs.

Most notably : the following line doesn't make any sense:
CD>             if cut == -1: cut = find(remaining, ' ', cut-1)
as cut-1 always will be -2 ...


here is an updated version with support for existing newlines as well:

from string import find, rfind, join

def wordWrap(text, width):
    remaining = text
    wrapped = []

    while len(remaining) > width:
        cut = width
        newline = find(remaining, '\n', 0, cut)
        
        if newline != -1:
            cut = newline
        elif remaining[cut] != ' ':            
            temp = rfind(remaining, ' ', 0, cut-1)
            if temp == -1:temp = find(remaining, ' ', cut-1, len(remaining))
            if temp == -1: temp = len(remaining)
            cut = temp
        wrapped.append(remaining[:cut])
        remaining = remaining[cut+1:]

    if remaining:
        wrapped.append(remaining)

    return join(wrapped, '\n')


thanks a lot , Casey
