========================================================================== 
    building
========================================================================== 

    To build sk_analysis_dump, do:

	./configure [options]
	make

    ./configure takes the following options in addition to the standard 
    options:

	--with-arts=DIR     use Arts in DIR (default: /usr/local/arts)
	--with-geode=DIR    use Geode in DIR (default: /usr/local/geode)
	--with-coral=DIR    use CoralReef in DIR (default: /usr/local/Coral)
	--with-netacuity=DIR    use Netacuity in DIR (default: netacuity_api)

    There have been compilation problems with the arts++ on Linux's gcc
    2.95.4.  Thye error messages look like:
	Error: invalid character (0xffffff9b) in mnemonic

    By turning off optimization this could be avoided.  When running
    arts++ configure command do:
	env CXXFLAGS="-Wall -Wpointer-arith -Wstrict-prototypes \
	-Wmissing-prototypes -Wwrite-strings -Winline" ./configure
