""" This is a Pre-0.5 to Post-0.5 Application Upgrade Script.
This program REWRITES your application - everything in the
entire current working directory - modifying the import statements.
The task of adapting applications is boring and laborious, so
why waste time when you can run this script, and it'll be done
in seconds.
Please ensure that you do not have any import statements in the following
syntax (do NOT use backslashes):
from pyjamas.ui import HorizontalPanel, \ <--
Older style statements such as 'from ui import HTML' are NOT covered but
if you wish to adapt this code to do so, make a second 'searchfor'
using 'from ui import ' instead of 'from pyjamas.ui import ' below.
**** WARNING ****
You are expected to take your own precautions to mitigate the destruction
of your source code, by utilising suitable protection measures such as
source revision control.
Absolutely no responsibility WHATSOEVER is, will or can be accepted for
your failure to take basic precautions, whether you have or have not
read, or have or have not accepted this warning.
