# @DESCRIPTION:

# Default pkg_setup function for packages that depends on qt3. If you have to

# create ebuilds own pkg_setup in your ebuild, call qt3_pkg_setup in it.

# This function uses two global vars from ebuild:

# - QT3_BUILT_WITH_USE_CHECK - contains use flags that need to be turned on for

#   =x11-libs/qt-3*

# - QT3_OPTIONAL_BUILT_WITH_USE_CHECK - qt3 flags that provides some

#   functionality, but can alternatively be disabled in ${CATEGORY}/${PN}

#   (so qt3 don't have to be recompiled)
