# Apparently the latest stable release of DCMTK, which is close to six years old but represents the
# only and still somewhat relevant reverse dependency of this package, cannot be bothered to use
# system CharLS at any other than the default location. Thus this package has to conflict with all
# other CharLS releases available right now.
