From cfb07cca7d9a517fae1bdc741c41c06d150a852f Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Sat, 2 Jun 2007 16:11:26 -0400 Subject: [PATCH] git-gui: Verify Tcl/Tk is new enough for our needs For quite a while we have been assuming the user is running on a Tcl/Tk 8.4 or later platform. This may not be the case on some very old systems. Unfortunately I am pretty far down the path of using the Tcl/Tk 8.4 commands and options and cannot easily work around them to support earlier versions of Tcl/Tk. So we'll check that we are using the correct version up front, and if not we'll stop with a related error message. Signed-off-by: Shawn O.
