[http://$server$/$home$/$file$](http://$server$/$home$/$file$)

To fully understand this template, you have to know something about HTML, a web
page description language that we’ll explore in Part IV. But for the purposes of this
example, you can ignore most of this file and focus on just the parts surrounded by
dollar signs: the strings $server$, $home$, and $file$ are targets to be replaced with real
values by global text substitutions. They represent items that vary per site relocation
and file.

Page Generator Script

Now, given a page template file, the Python script in Example 6-8 generates all the
required forward-link files automatically.

Example 6-8. PP4E\System\Filetools\site-forward.py

"""
################################################################################
Create forward-link pages for relocating a web site.
Generates one page for every existing site html file; upload the generated
files to your old web site. See ftplib later in the book for ways to run
uploads in scripts either after or during page file creation.
