# TODO:
# host staging - some programs need to build and execute Qt apps during build
# enable more features - glib support causes link failures on ARM, possibly
#	other targets, javascript JIT, webkit and the unixodbc driver are not
#	compiled
# split build - separate net, sql, possibly individual sql plugins from core
#	libraries, probably only core should ever need host staging

# QT-EMBEDDED_VERSION, QT-EMBEDDED_SITE and QT-EMBEDDED_SOURCE define
# the upstream location of the source code for the package.
# QT-EMBEDDED_DIR is the directory which is created when the source
# archive is unpacked.
# QT-EMBEDDED_UNZIP is the command used to unzip the source.
# It is usually "zcat" (for .gz) or "bzcat" (for .bz2)
#
# You should change all these variables to suit your package.
# Please make sure that you add a description, and that you
# list all your packages' dependencies, seperated by commas.
