[Zope] Script to do various 'manage_' operations

[Tim Hicks]

I have been trying to get hold of a script that can automatically convert
various dtml methods to custom zclass instances.  I found a script on the
zope mailing list (see bottom)

I put my file (see below) in the Extensions directory and added an external
method from within zope.  This all appeared to go fine.  To execute the
script, I made a method that simply had <dtml-call conscript()> and then
standard_h_h etc.  The problem is, nothing seems to happen.  I can view the
method that was supposed to run the script, but the call doesn't seem to
work.  Within the filesystem, there is no file called tempo (as a kind of
log of what's been done), and the methods with extension .shtml certainly do
not get changed to dtml documents.

Has anyone done this before?  Can you shed any light on what I'm doing
wrong?

Much obliged.
