The remainder of this chapter consists of an introductory tutorial on FunnelWeb. Ideally you should have a working version of FunnelWeb in front of you when reading this chapter so that you can try out the examples yourself. There is no need to try all the examples so long as you type in enough to feel comfortable with what you are reading. There is no harm in reading this chapter offline too, so long as you get to the computer within a couple of days to reinforce what you have read.
For best effect, you should create a new, temporary, empty directory in which to experiment with FunnelWeb. That way, it will be more obvious when FunnelWeb creates an output file. You can either type in the examples in this chapter directly, or copy and paste them from the LATEX source file for this chapter or the FunnelWeb test suite. The source file for this chapter should be available in a file such as /fwdir/userman/ch1.tex. The test suite should be available in a directory such as /fwdir/tests/. The test files called ex01.fw through ex16.fw contain the examples in this chapter. The test files called hi01.fw through hi10.fw contain the examples in the next chapter.
If you do not yet have an installed copy of FunnelWeb, refer to
Chapter for full details on how to obtain and install
a copy of FunnelWeb. If you are not sure if you have an installed copy,
try invoking FunnelWeb by giving the command fw. If this yields an error
such as command not found then you do not have a properly
installed version of FunnelWeb.
