<P>This page contains a brief hands-on tutorial to get you started
in using FunnelWeb to make webs.
<P><BR><FONT SIZE="4"><STRONG>Hello Web</STRONG></FONT><BR>
<P>The best way to understand how FunnelWeb can help you make webs
is to work through a simple example. Here is one:
<P>
<PRE>

@!************************************************
</PRE>
<P>Cut and paste the above text into a file called <SAMP>dave.fw</SAMP>
and run FunnelWeb on it by giving the command:
<P>
<PRE>
fw dave
</PRE>
<P>
<BLOCKQUOTE>
<FONT SIZE="2">
<STRONG>Note:</STRONG> On my computer, when you cut and paste text
from a web page, the pasted text contains a block of blanks
before each line; you will have to delete these to make the
example work, as FunnelWeb requires the first line of macro
definitions to be in column one.
</FONT>
</BLOCKQUOTE>
<P>If all goes well, FunnelWeb should write out two files
<SAMP>index.html</SAMP> and <SAMP>links.html</SAMP>. That's the
generated web, and you should be able to browse it using your
favorite web browser.
<P><BR><FONT SIZE="4"><STRONG>First Glimmers Of Usefulness</STRONG></FONT><BR>
<P>The sole benefit we have obtained so far is that the web
is represented as a single file. This confers quite a few benefits
on its own for medium-sized webs, such as the elimination of
the need to perform multiple-file search and replace operations,
but it's really only a start.
<P>The next step is to recognise that the two pages above share
quite a lot of text and that that text can be removed into FunnelWeb
macros.

<P>Now, although the file has actually got a little longer and
looks far more complicated than it did, we've actually managed
to extract two significant benefits from this reorganization.
<P><BLOCKQUOTE><B>Page style:</B> First, almost without even
trying, we've created a page style. For example, to change
the colour of all the pages in the web, we need just change
the single body definition in the begin page macro.
Similarly, if we wanted to add a copyright notice at the
bottom of each page, we need change only the end page
macro.</BLOCKQUOTE>
<P><BLOCKQUOTE><B>Page overhead:</B> Second, we've reduced the
amount of text required to define each page. Instead of
requiring ten lines of HTML to set up each page, we need
just two FunnelWeb calls (two lines); the rest is text
particular to the page being defined.</BLOCKQUOTE>
<P>These advantages may seem minor, but when scaled up to a
web containing a dozen or more pages, they become very significant.
<P>The newfound power, in the case of the example, can be demonstrated
by changing the web from black on white to blue on white, and by adding
another page:
