# This scripts builds a static version of skip_server and skip_printer.
# Static in the sense that the resulting binaries will not attempt to load
# any dynamic library (cf -static option of clang).
#
# The only reason to build those binaries is that they will be much easier
# to distribute. When you link with a dynamic library, you need the same
# library to be available on the system that will run the binary.
#
# That can be difficult to get right, especially when you have quite a few
# of them.
