"""cups-config wrapper.
cups-config, at least on Ubuntu Lucid and Natty, dumps all
cflags/ldflags/libs when passed the --libs argument. gyp would like
to keep these separate: cflags are only needed when compiling files
that use cups directly, while libs are only needed on the final link
line.
TODO(evan): remove me once
https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/163704
is fixed.
