####################### V 1.4.0.2:
corrections:
exec'd write-only addresses get a chance to flush before being killed
error handler: print notice on error-exit
filan printed wrong file type information
####################### V 1.4.0.1:
corrections:
socks4a constructed invalid header. Problem found, reported, and fixed
by Thomas Themel, by Peter Palfrader, and by rik
with nofork, don't forget to apply some process related options
(chroot, setsid, setpgid, ...)
####################### V 1.4.0.0:
new features:
simple openssl server (ssl-l), experimental openssl trust
new options "cafile", "capath", "key", "cert", "egd", and "pseudo" for
openssl
new options "retry", "forever", and "intervall"
option "fork" for address TCP improves `gender changer´
options "sigint", "sigquit", and "sighup" control passing of signals to
sub process (thanks to David Shea who contributed to this issue)
readline takes respect to the prompt issued by the peer address
options "prompt" and "noprompt" allow to override readline's new
default behaviour
readline supports invisible password with option "noecho"
socat option -lp allows to set hostname in log output
socat option -lu turns on microsecond resolution in log output
corrections:
before reading available data, check if writing on other channel is
possible
tcp6, udp6: support hostname specification (not only IP address), and
map IP4 names to IP6 addresses
openssl client checks server certificate per default
support unidirectional communication with exec/system subprocess
try to restore original terminal settings when terminating
test.sh uses tmp dir /tmp/$USER/$$ instead of /tmp/$$
socks4 failed on platforms where long does not have 32 bits
(thanks to Peter Palfrader and Thomas Seyrat)
hstrerror substitute wrote wrong messages (HP-UX, Solaris)
proxy error message was truncated when answer contained multiple spaces
porting:
compiles with AIX xlc, HP-UX cc, Tru64 cc (but might not link)

and slightly modified by me.
socat is a relay for bidirectional data transfer between two
independent data channels. Each of these data channels may be a file,
pipe, device (serial line etc. or a pseudo terminal), a socket (UNIX,
IP4, IP6 - raw, UDP, TCP), an SSL socket, proxy CONNECT connection, a
file descriptor (stdin etc.), the GNU line editor, a program, or a
combination of two of these. These modes include generation of
"listening" sockets, pipes and pseudo terminals.
