# qt-4.8.7 is built from The Qt Company source, with lots of patches
# from various sources.

# This is the SBo-ized version. Heinz Wiesinger (pprkut) got this
# to build on Slackware-current as of January 23, 2021. The stuff
# in patches/ was collected (and in a few cases written) by him,
# and he worked out the correct order to apply them. B. Watson
# (urchlay@slackware.uk) modified pprkut's version to make it fit the SBo
# template, and to make it install to /usr/lib(64)?/qt4/ to stay out of
# the way.

# 20220409 bkw: BUILD=2
# - forgot to put the SlackBuild in the doc dir.
# - resize icon correctly so it's really 48x48.
# - get rid of Encoding from .desktop files (deprecated).

# 20220302 bkw: webkit already wasn't being built, even with the
# -webkit option passed to configure, so update the script to remove
# the option to disable it (it's always disabled), and update the
# README to document that fact.
