Website build script

Hi all,

The following script is currently used to build our main website. Static
HTML versions of each of the pages are generated from php scripts on an
hourly basis by this script, but the other day for some reason it
generated an empty index page, but gave no errors that we have been able
to find.

We've more or less resigned ourselves to this being a glitch, but
figured it wouldn't hurt to get a few extra sets of eyes over the script
anyway. Any comments or suggestions for improvements would be
appreciated.

Regards, Dave.
