## Running Test Commands in Shell
## ------------------------------
##
## Selected TCL procedures from the automated tests
## have been made available in the shell.  When run from the shell,
## the actual TCL procedure is still run, with some setup.
## Arguments for each command are identical to those of the TCL version.
## The result from the given command is returned on stdout, (possibly along
## with additional information preceeding it)
##
## The arguments are identical to those provided within TCL, however because
## of quoting differences, shell " or ' quotes should guard each argument
## For example:
##	In TCL: some_proc {{1} {my.file}}
##	In Sh:  some_proc "{1} {my.file}"
##
## The running of such commands in the shell assumes settl and TEST_CONFIG_FILE
## have been setup
##
## At present the following commands are available in the shell:
## some typical uses:

# This shell script is a simple interface for shell scripts to run the
# a tcl function from the automated test environment.
# typically it is invoked via tcl_proc, which also sets up common
# environment variables such as TCLLIBPATH

# This script can be linked to filenames correspnding to what ever TCL commands
# need to be available from the shell.
# alternately a tcl function name can be provided as the first argument to
# this script when this script is invoked as "front"
# such as:
#	front get_config CFG_HOSTS

if { ! [ info exists env(TL_DIR) ] || $env(TL_DIR) == "" } {
        puts stderr "$argv0: run settl first"
        exit 1
}

# This is a workaround for MAC, which does not support TCLLIBPATH
# it doesn't hurt on Linux.  ibtools.exp sources all our .exp scripts
if { [ file exists $env(TL_DIR)/TestTools/ibtools.exp ] } {
	# HostTests
	source $env(TL_DIR)/TestTools/ibtools.exp
} else {
	# Fast Fabric, TL_DIR is set to /usr/lib/eth-tools
	source $env(TL_DIR)/ibtools.exp
}

if { ! [ info exists env(TEST_SHOW_CONFIG) ] } {
