Yup, apparently @INC = (@INC,"/usr/local/tools/lib"); won't work. Lessee
what to do...

I don't see the need to perform the h2xs command. Does it help automate
creating the pm file?

Ok, do this instead:
In the script, include the following line:
use lib "/usr/local/tools/lib";

Yes, it creates a skeleton pm for you, along with Makefile.PL etc.
h2xs -X -n Modulename I think -- but I am inexperienced in the ways of
modules.

Yes. There are other alternatives which may be better; see the FAQ.

Well, AFAIK there's HTML::LinkExtor (part of HTML::Parser), that allows you
to extract links from an HTML page, and there's LWP::UserAgent and
LWP::RobotUA (part of LWP aka libwww-perl) that allows you to grab
webpages. They're available from CPAN, if you don't have them yet.
That should give you a good start...
And there are probably some ready-made scripts available for free
somewhere on one of the Perl and/or CGI repositories on the web.
Michel.

Loads. You might take a look at Randal Schwartz' columns at :
<http://www.stonehenge.com/merlyn/WebTechniques/>
where I know there is at least one example that does that very thing.

Subject: Loading modules
Message-Id: <8074mu$bkp$1@nnrp1.deja.com>
I wrote a PERL script that requires the loading of modules. In UNIX,
the script is able execute perfectly but when I click on the file using
Netscape browser, I get a server Error message. The S.A. told me that
it has something to do with the ENV.
background information: The web browser is executing under the login
NOBODY.
My impression of this is that the server's ENV PATh is undefined. My
questions are
1) How can I defined it?
2) How can I load the modules during the web browser session?

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
| NOTE: The mail to news gateway, and thus the ability to submit articles
| through this service to the newsgroup, has been removed. I do not have
| time to individually vet each article to make sure that someone isn't
| abusing the service, and I no longer have any desire to waste my time
| dealing with the campus admins when some fool complains to them about an
| article that has come through the gateway instead of complaining
| to the source.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
