Yes, works really well. :stuck_out_tongue:

What about the thing for matching lower and upper case letters?

while [ "$#" -gt 0 ]
do

  arg=`echo "$1" | tr '[:lower:]' '[:upper:]'`

  case "$arg" in

  "--RAYTRAC-PATH")
    shift     # Skip ahead one to the next argument.
    arg_raytracPath="${1}"
    opt_raytracPath=1
  ;;

  "--CMODIF"|\
  "--CMOD-INFILE")
    shift     # Skip ahead one to the next argument.
    arg_cmodInFile="${1}"
    opt_cmodInFile=1
  ;;

...

or

while [ "$#" -gt 0 ]
do

  case "$1" in

  "--"[rR][aA][yY][tT][rR][aA][cC]"-"[pP][aA][tT][hH])
    shift     # Skip ahead one to the next argument.
    arg_raytracPath="${1}"
    opt_raytracPath=1
  ;;

  "--"[cC][mM][oO][dD][iI][fF]|\
  "--"[cC][mM][oO][dD]"-"[iI][nN][fF][iI][lL][eE]")
    shift     # Skip ahead one to the next argument.
    arg_cmodInFile="${1}"
    opt_cmodInFile=1
  ;;

...

Yes, no reason you can't do [aA] in those.
