Call a Mathematica program from the command line, with command-line args, stdin, stdout, and stderr

Solution
MASH -- Mathematica Scripting Hack -- will do this.
Since Mathematica version 6, the following perl script suffices:

For previous Mathematica versions, a C program is needed:

UPDATE: At long last, Mathematica 8 supports this natively with the "-script" command-line option:

Problem
If you have Mathematica code in foo.m, Mathematica can be invoked with `-noprompt` and with `-initfile foo.m` (or `-run "<<foo.m"`) and the command line arguments are available in `$CommandLine` (with extra junk in there) but is there a way to just have some mathematica code like ``` #!/usr/bin/env MathKernel x = 2+2; Print[x]; Print["There were ", Length[ARGV], " args passed in on the command line."]; linesFromStdin = readList[]; etc. ``` and chmod it executable and run it? In other words, how does one use Mathematica like any other scripting language (Perl, Python, Ruby, etc)?
