% The following 2 procs encapsulate the jobs to be processed
% much as is done with EPS images:
/_begin_job_
{
        /tweak_save save def
        /tweak_dc countdictstack def
        /tweak_oc count 1 sub def
        userdict begin
}bind def

/_end_job_
{
        count tweak_oc sub{pop}repeat
        countdictstack tweak_dc sub{end}repeat
        tweak_save restore
}bind def

% Now, add your jobs like this:

EOF
    local -i i=0
    while [ $i -lt ${#src_list_array[*]} ]; do
        echo "_begin_job_"
        echo "(${src_dir_array[$i]}/${src_list_array[$i]}) run"
        echo "_end_job_"
        echo
        let i++
    done

    echo "% and so on."
