Shell compilers

[Carl Dichter]

I am looking for compilers for shell scripts.

I am particularly intrested in Bourne shell compilers,
but you can send me information on any shell language compilers.

I'll post a summary.

Thanks in advance,

PS: I realize that you can use "#!/bin/sh" at the start
of the file to cause it to be interpreted by the correct
shell, but a compiled shell script is prefered for speed
and source protection.
