Use gp-runtime as a filter

["Ruud H.G. van Tol" <rvtol@isolution.nl>]

I'm very used to using CL-tools as filter,
reading from stdin and writing to stdout.

Is that easy to achieve with the current gp?

I didn't find details about it.

Would also be nice if there was a minimal "gpf" variant,
that only pre-loads/pre-processes what is requested,
so a script can start with
  #!/usr/local/bin/gpf
and by default reads lines from stdin,
and prints to stdout.

#!/usr/local/bin/gp
as the start line in an executable text file,
just works, but I got into trouble
when I started gp with output piped to less.

Am also still looking for a pager.
In for example the MySQL client, I generally do
\P less -inSX
as my first command,
whenever I use it interactively.
(never bothered to set that up in the environment)

Will now check what readline offers in that area.

xargs, and then run 40 gpf's, side by side,
would then also be a nice test ...
(even better if they can share read-only memory)
