No, that's not what I said.

You can call *any* script (by specifying a full path to it), but be aware
of two things: 1) tcl will not understand POSIX paths, so you have to use
Win32 paths, and 2) Windows doesn't treat shell scripts as executable, so
you have to use 'sh' to move over to the Cygwin world (which will,
incidentally, understand POSIX paths).

For example, you can call *any* program (or batch file) directly by
specifying a full Win32 path to it (e.g., 'c:\cygwin\home\foo\prog.exe').
However, if you call a script (with a '#!' magic) instead, Windows won't
know what to do with it, so you have to call a shell (e.g., 'sh') to
interpret the invocation (e.g., 'sh /home/foo/prog.pl').  In both cases,
the program or script doesn't have to be in the path, as long as you
provide a full path to the script.  In the first case (direct call) it's a
Win32 path, and in the second (call through shell) it's a POSIX path.
