#==============================================================================
# IMPORTANT NOTE
#
# Before updating to a new version from upstream, please test building with
# +contrib, in addition to the default. Reason being, the extra functionality
# is used by many, including our own MacPorts members. Enough so that we may
# want to enable +contrib by default at some point.
#
# Also note that upstream has occassionally broken the Contrib build, so it's
# not a given that it will compile successfully.
#
# Net-Net: If upstream breaks Contrib for a certain release, please don't
# update to it. And submit a ticket for the issue, if none exists.
#
# Thanks!

description         Open Source Computer Vision Library
long_description    OpenCV (Open Source Computer Vision Library) is an \
                    open source computer vision and machine learning \
                    software library. OpenCV was built to provide a \
                    common infrastructure for computer vision \
                    applications and to accelerate the use of machine \
                    perception in the commercial products. Being a \
                    BSD-licensed product, OpenCV makes it easy for \
                    businesses to utilize and modify the code.
