Easy solution in awk:

Code:
#!/usr/bin/env ksh
awk '
        NF > 1 {
                for( i = 2; i <= NF; i++ )
                        printf( "%s %s\n", $1, $(i) );
        }
' <input_file

Strictly using shell commands:
Code:
while read name list
do
    for c in $list
    do
        echo "$name $c"
    done
done <input file

       cat << EOF > test.awk
       @include getopt.awk
