Using Text::Template and LaTeX isn't a bad idea for creating reports. BTW, what does "autonomously" mean in this context?

Update:

Instead of one of the templating modules you can also use this technique i cheated a while ago:

#!/usr/bin/env perl                                                   
+                          

use strict;
use warnings;

undef $/;

my %vars = ( name  => qq(Karl),
             color => qq(blue),
             fruit => qq(tomato)
           );

my $string = <DATA>;

$string =~ s/%%(.*?)%%/$vars{$1}/gs;

print $string;

__DATA__
Hello, my name is %%name%%!                                           
+                          
May i have a %%color%% %%fruit%% please?

Perhaps i posted this already but cannibalisation isn't a bad idea :-)
