#This is an automated script to add anti-aliasing support to aMSN. This
# will compile the latest beta of Tcl and Tk, and recompile aMSN for it.
#
#A few notes:
#
# - The beta Tcl and Tk will be compiled and installed into /usr/local;
#   it will not replace your existing Tcl and Tk installation, so it
#   should be much safer to use and easier to revert than other methods.
#   If the script fails for whatever reason, your existing aMSN
#   installation will not be harmed.
#
# - If aMSN complains about a missing TLS library when you try to log
#   in, choose "Don't download TLS, I'll install it myself", then click
#   Account->Preferences->Advanced, and in the Other section there will
#   be a box labeled TLS; paste this in it: /usr/lib/tls1.50
#
# - A hold will be placed on the amsn package in apt-get so that it
#   doesn't upgrade automatically. If you want to upgrade when a new
#   version comes out, you will need to apt-get install the new package,
#   then download the source code and compile it as in this script.
#
# - Certain icons will still look ugly in the default skin; this script
#   will automatically add the Ubuntu and Kubuntu skins by GuS-Arg. You
#   can activate them via Account -> Preferences -> Appearance ->
#   Select Skin.
#
# - If you want to revert to the normal aMSN, simply open a console and
#   type:
#     sudo apt-get remove --purge amsn
#     sudo rm -r /usr/share/amsn
#     sudo apt-get install amsn
#
#This script was written for [k/x]Ubuntu Edgy. Use at your own risk.
