68878 text randomizer program

Hi. I'm looking for a simple desktop program for windows XP that takes a text file with one sentence each line and mixes them up and create an output file with random sentence on each line. Here is step-by-step instruction of what it does. 1. The input file is a text file with one sentence per line. 2. The program randomizes the sentences and create an output file with one sentence per line. 3. The program has an option of inserting a delimiter between the sentences (lines). If there's none, it will write one sentence for each line. * Interface would consis of text box for 1. Input File (with browse button) 2. Output File (with browse button) 3. Optional Delimiter box where you can enter the delimiter of your choice - for example, additional line, -----, %%, NEXT, (br) etc. * Additional requirements. 1. You have the choice of selecting a language. However it has to be stable and do not crash the window (hopefully...). Must work without installation. 2. Must run fast. 3. Must be handle a large data. I know this is not an ideal solution to work with flat data file. But it must be able to handle a large data, say about 1 million lines or more. 4. High degree of randomness If you want, you can finish it today and get paid right away. Thank you for your interest.
