The source code pasted above are indeed of a preview nature; the more
formal documentation will probably be written in the internal testing
here. recordln works quite like recordio and the command line usage
are identical; the former is just more line-oriented. The command line
usage of iotrap and ipctee are printed when `-h' is given; below is a
brief summary of them.
iotrap works like the trap program from execline, but the signals
currently cannot be customised. When iotrap receives a terminating
signal, the spawned subprocess is sent an EOF; after this, if the
subprocess does not exit before the timeout tunable by the `-t' option,
the previous signal is forwarded.
ipctee listens to a pair of input and output sockets, the first accepts
at most 1 connection and the latter multiple connections. (The input
socket is for the IOC; the output socket is for "procServ clients".)
For each connected client, the bytes it writes are forwarded to all
other clients connected at the time.
(You may realise ipctee is essentially a "chatting server" for all
connected clients, and it may seem that ipctee can be furtherly
simplified by eliminating the input socket and treating all clients
fully equal. However, for certain use cases, we may disallow writes
from the output socket; this is why there is a `-r' option for the
"readonly" mode, and why the program is called "ipctee" not "ipcchat".)
