See README.html and the man page for more information about grid-updates.
Python version 2.6 and later, not including Python 3.0 or 3.1. A Python installation is not required for Windows users when using the py2exe version.
Those with a supported version of Python can install grid-updates with the command python setup.py install from within the source archive.
Debian users can build packages with the command fakeroot debian/rules binary. This will build a package that can be installed using dpkg. This package will include the script and its documentation.
Windows users have the following available options:
In short: if you're running Windows and don't know which file to get, download the py2exe version.
Consider running grid-updates --patch-tahoe after installation (not yet available for Tahoe-LAFS 1.10). This will apply a small patch to Tahoe-LAFS's web console to allow displaying news from grid-updates in an Iframe. The web console can be restored to its original state with grid-updates --undo-tahoe-patch.
In order for this script to work, it needs to have read and write permission for the Tahoe-LAFS node's directory. This directory is typically located at %APPDATA%\.tahoe for Windows users and ~/.tahoe for other systems.
If asked to, grid-updates will update your introducers file and make a backup of it. When fetching NEWS, the script will write a plain text version to ~/.tahoe/NEWS. Additionally, an HTML version and an Atom news feed will be saved to your Tahoe node's web.static directory (typically ~/.tahoe/public_html). NEWS.html and NEWS.atom can be viewed in the node's /static directory, or (having patched Tahoe's Web UI) right on your node's front page
