#
# This is a wrapper-script for starting FreeOrion on
# ix86 (and maybe x64) Linux Systems.
# This script will CD into application and set some
# enviroment variables.
# ---- commandline PARAMETERS and ENVIROMENT variables -----
# This script supports parameters, that will be evaluated
# BEFORE freeorion binary is called and will be removed,
# because the binary won't support them.
# Currently only one parameter at a time is supported!
# Parameters other than these will be appended as command
# line parameters to the call of the freeorion binary.
#
# --strace
# This starts freeorion using the "strace" utility.
# Generates a strace logifle /tmp/freeorion.trace.
# Make sure it is installed on your system!
# --gdb
# Runs freeorion in a gdb instance, passes the original
# parameters through the --args parameter of gdb
#
#
# ENVIROMENT variables
# This script supports some enviroment variables. To set them
# either use the followin command BEFORE you execute this script.
# export XXXX="value"
# This permanently set the variable in you current shell script.
# Or you prepend the options when running this script, like this:
# PARAM1="hello" PARAM2="yo man" /usr/bin/freeorion.elf
#
# Supportet are:
# FO_TRACE=
# Use this to prepend something to calling freorion.
# This variables also is used internally, when --gdb or --trace
# appear on the command line.
# FO_GDB_ARGS=
# If you use --gbd, you should uses this env to add GDB parameters.
# Make sure you end this list of parameters with --args, otherwise
# gdb won't start. Example: FO_GDB_ARGS="-q -s fo.symbols --args"
# LD_LIBRARY_PATH=
# This is a well known env and will be honored by this script.
#
# ---------- STARTS HERE ---------------
# Change into application directory
# If this is a symlink, then we
# need to change into the dir of symlink-target.
