# Load the emc.tcl file, which defines variables for various useful paths
source [file join [file dirname [info script]] emc.tcl]

# Tk GUI for the Enhanced Machine Controller

# Notes

# 1. Widget focus. Keyboard traversal with TAB sets the focus to some of the
# widgets. When they're focused, arrow keys and numbers don't work. To fix
# this, most widgets that would get focus have the focus disabled with
# -takefocus 0. A few remain; these are added to the widgets that bindtags
# applies to when switching between ManualBindings, AutoBindings

# 2. Adds tkbackplot and scripts to menu.
# 3. Adds info to help menu that calls tcl.sysinfo.tcl and uses emc/emcversion

# Set global that signifies we're the tkemc, so that other sourced scripts
# can know how to pack themselves. This lets these scripts pack into the
# main window "." if "tkemc" is not defined, or in their own top-level window
# if "tkemc" is defined. emclog.tcl looks at this.
set tkemc 1

# Internationalisation (i18n)
# in order to use i18n, all the strings will be called [msgcat::mc "string-foo"]
# instead of "string-foo".
# Thus msgcat searches for a translation of the string, and in case one isn't 
# found, the original string is used.
# In order to properly use locale's the env variable LANG is queried.
# If LANG is defined, then the folder src/po is searched for files
# called *.msg, (e.g. en_US.msg).
