# This script replaces the actual optipng binary so a command like:
# optipng -strip all -clobber -o 7 -out outputfile -fix -i 0  inputfile
# which pgadmin uses during the build process, actually uses pngcrush to
# compress png files. Note that all parameters are ignored and the
# default pngcrush parameters are used instead.
