I'm happy to present you another kind of perl-bot, that should be a valuable addition to our bot-section. I thank Bernd and/or The Mystical Friend for this excellent contribution.
Please send all feedback and amelioration proposals to both The Mystical Friend (mystend(at)yahoo(point)com) and myself, I'll publish if worth.

#!/usr/local/bin/perl -I.  ## -I. stands for Include . (you understand later why)
## This is a very special kind of a Robot. You can start
## ---------------------------------------------------------------
##                    M I R B O T   1. 0
## ---------------------------------------------------------------
## this one from a free cgi-bin service like virtualave or netfirms remotly
## with a browser. You need only a start_cgi script, which opens a new shell
## e.g.    #!/usr/bin/perl -I.
##         system(./bot.cgi?xyz); #xyz stands for the parameters
## So and here is how it works:
##         You give the bot an URL (e.g. http://129.105.116.5/fravia/index.html),
## Username and Password for a FTP-Account, and an E-mail Adress for statisical
## reasons. First the bot downloads the index.html, then he parses the doc. and
## after that, he loads the docoment up to the Ftp Server. This can be
## used for automatical mirroring. When the bot has finished, he sends you an
## E-mail (over sendmail). This Mail tells you about the errors, how many and 
## which kind of files has been uploaded.
## Installation: Upload all standard perl modules into the cgi-bin Directory,
## then upload the bot, and finally upload a little File and rename it to "live"
## (read the source and the comments why).
##
## Hmm the bot worked fine after programming; He is tested
## well, and no bugs has been found.
## Tips for newbies: Learn Perl, and you can write bots like this one.
