Description: | Is your Personal Nodelet getting too big? Mine sure Also, check out Personal Nodelet Restorer. Comments and improvements always welcome. :)
Fixes: UPDATE: - after gleaming good security info from jcwren, i changed this script to accept an interactive password similiar to how mysql asks for passwords: you can specify the password on the command line with the -p option (dangerous for mulit-user boxes), or you can just specify -p by itself and be prompted for the password. I use Term::ReadKey to keep the password 'invisible'. Because of the new nature, be sure and specify -p last, after -u and -s if used. UPDATE (Mar 24,2002): - somebody moved 'lastnode' before 'node' so regex has been updated |

=head1 NAME
extract_personal_nodelet.pl - LWP script
=head1 DESCRIPTION
This is a simple script that uses LWP and HTML::TokeParser to
access your User Settings page and extracts your Personal
Nodelet links.
=head1 SYNOPSIS
for *nix:
./extract_personal_nodelet.pl -u uname -s : -p
for win32:
perl extract_personal_nodelet.pl -u uname -s : -p
Invokes the script for the specified username and use a
colon as the record separator. The script will prompt
you for your password if you do not specify it. The
contents would look something like this:
24270:Permutations and combinations
25730:Life in the land of OOP, and I'm confused.
17890:Shift, Pop, Unshift and Push with Impunity!
32005:Apache::MP3
34786:Why I like functional programming
The default record seperator is a tab. I recommend you use it
since just about any character is fair game for a node title.
