INSTALL

It's simple. You need to have patch utility on your system. If you have linux or other unix, you most probably already have one. If your zope is on windows, you should find that utility somewere on the web...

on unix, put stx_i18n-x.y.z.patch in your lib/python/StructuredText directory in zope installations dir, go to that directory in your terminal and run:

  patch -p0 < stx_i18n-x.y.z.patch

On my system i do:

  cd /usr/lib/zope/lib/python/StructuredText
  patch -p0 < stx_i18n-0.9.9.patch

And got this output:

  patching file DocumentClass.py
  patching file DocumentWithImages.py
  patching file HTMLClass.py
  patching file ST.py

After that you should restart zope.

On windows system operation should be very similar, you only should find a patch program...
