 *** IMPORTANT ***

This is an unstable version of xedit.
It is for test purposes only.

Please, DO NOT use it in a production environment.
It will probably crash and you will lose your data.

If you are looking for a stable release of xedit, either download
it from:

  http://pub.mate-desktop.org/release/1.${stable_version}/

Or checkout the 1.${stable_version} branch of the xedit module from:

  git://github.com/mate-desktop/xedit.git

Thanks,
