=head1 Convert Tabbed Representation of Sets to Numbered Relational Representation

This script takes as input a tab-delimited file of sets, with each set being one
record in the file. It outputs a two-column tab-delimited file where the first
column is the set number and the second column is a set member. Thus, if the
input file is

    a       b       c
    d       e
    g       h

The output would be

    1       a
    1       b
    1       c
    2       d
    2       e
    3       f
    4       g
    4       h

The optional positional parameter is the number to give to the first set. The default
is C<1>.


my $usage = "usage: tabs2rel [InitialN] < tab-sep-sets > relation";

my $n = (@ARGV > 0) ? $ARGV[0] : 1;

while (defined($_ = <STDIN>))
    foreach $x (split(/\t/,$_))
        print "$n\t$x\n";
