-/* redir.c: code for opening files and piping heredocs after fork but before exec. */
-
-#include "rc.h"
-
-/*
-   Walk the redirection queue, and open files and dup2 to them. Also,
-   here-documents are treated here by dumping them down a pipe. (this
-   should make here-documents fast on systems with lots of memory which
-   do pipes right. Under sh, a file is copied to /tmp, and then read
-   out of /tmp again. I'm interested in knowing how much faster, say,
-   shar runs when unpacking when invoked with rc instead of sh. On my
-   sun4/280, it runs in about 60-75% of the time of sh for unpacking
-   the rc source distribution.)
