# NOTE: this is extremely unfinished.  It is intended to demonstrate
# how to handle a fully dynamic command set in ShellUI.


# psh is intended to be a fully interactive Perl shell (not in the
# sense of Bash, but in the sense of running Python with no args) or irb.
#
# Supply a Perl expression on the command line and Perl will evaluate
# it and exit.  Otherwise, it will drop you into the interactive shell.


if(@ARGV) {
	print eval join(' ', @ARGV), "\n";
    exit(0);
}

# if no arguments then enter interactive shell.
