=NAME

generate_web_pages.pl - generate the web pages for the install site

=SYNOPSIS

Yeah, it does that.

Basically, there's a few comments in shell.html that we replace with
    what we really want in the files. Pretty simple.

The point of this is to look like the main site.

<p>LON-CAPA is based upon a lot of Open Source modules, so it's important
to have the right environment on your computer. Since it will frequently 
be the case that LON-CAPA will be going onto a dedicated machine, we've 
included instructions for installing LON-CAPA concurrently with new
installations of some of the popular Linux distributions.</p>

<p>A tarball installation is also available for those who wish to 
install on other distributions. Currently, Apache 1.x is required;
LON-CAPA does not yet run on 2.0.</p>

<p>For all distributions, please see how to 
<a href="config.html">configure the server after installation</a>.</p>
