   8 # This is a wrapper-script for starting FreeOrion on
   9 # ix86 (and maybe x64) Linux Systems.
  10 # This script will CD into application and set some
  11 # enviroment variables.
  12
  13 # ---- commandline PARAMETERS and ENVIROMENT variables -----
  14 # This script supports parameters, that will be evaluated
  15 # BEFORE freeorion binary is called and will be removed,
  16 # because the binary won't support them.
  17 # Currently only one parameter at a time is supported!
  18 # Parameters other than these will be appended as command
  19 # line parameters to the call of the freeorion binary.
  20 #
  21 # --strace
  22 #   This starts freeorion using the "strace" utility.
  23 #   Generates a strace logifle /tmp/freeorion.trace.
  24 #   Make sure it is installed on your system!
  25 # --gdb
  26 #   Runs freeorion in a gdb instance, passes the original
  27 #   parameters through the --args parameter of gdb
  28 #
  29 #
  30 # ENVIROMENT variables
  31 # This script supports some enviroment variables. To set them
  32 # either use the followin command BEFORE you execute this script.
  33 #    export XXXX="value"
  34 # This permanently set the variable in you current shell script.
  35 # Or you prepend the options when running this script, like this:
  36 #    PARAM1="hello" PARAM2="yo man" /usr/bin/freeorion.elf
  37 #
  38 # Supportet are:
  39 #   FO_TRACE=
  40 #      Use this to prepend something to calling freorion.
  41 #      This variables also is used internally, when --gdb or --trace
  42 #      appear on the command line.
  43 #   FO_GDB_ARGS=
  44 #      If you use --gbd, you should uses this env to add GDB parameters.
  45 #      Make sure you end this list of parameters with --args, otherwise
  46 #      gdb won't start. Example: FO_GDB_ARGS="-q -s fo.symbols --args"
  47 #   LD_LIBRARY_PATH=
  48 #      This is a well known env and will be honored by this script.
