This page still has documentation for tl-has-gnome-2 and tl-unity-2d: https://www.cendio.com/resources/docs/tag-devel/html/commands.html These scripts were removed on bug 4483 back in 2014.
Actually, tl-has-gnome-2 was removed for bug 5100.
I can verify that the documentation has be updated and that the information of the deleted scripts is gone. What I did: - Searched in the old documentation, only Chapter 13 was effected. - In new Chapter 13 they are removed. - grep the script names in thinlinc source tree Closing
