# Merged some ideas from Alex Sarmardzic's script for qt4 at SlackBuilds.org
# ^^ Modified by Robby Workman <rworkman@slackware.com> for QT4 & KDE4

# We're using qt-copy instead of a released qt version, as this git release
# has at least one bugfix strongly recommended by the kde developers.

# Obtained from:
# git clone git://gitorious.org/+kde-developers/qt/kde-qt.git
# git checkout origin/4.5.3-patched
# git checkout origin/4.6.0-stable-patched
# git checkout origin/4.6.1-patched
# git checkout origin/4.7.0-patched
#
# Alternate method (we don't use this):
# wget http://qt.gitorious.org/qt/kde-qt/archive-tarball/4.6.2-patched
#
# Modifications 2010, 2011, 2012  Eric Hameleers, Eindhoven, NL
# qt 4.7.3, 4.7.4, 4.8.0, 4.8.1, 4.8.2, 4.8.4 are built from original nokia sources.

# This is the highly modified version qt.SlackBuild found in Slackware
# tailored to Qt 5. Modified by Larry Hajali.
