#* ----------------------------------------------------------------------- *
#* Half an effort to create a color 'ls' script for AIX WITHOUT having to  *
#* install the GNU ls (which does support color).  Lots of room for        *
#* improvement.                                                            *

#* the grep -v is in case this is issued in home dir - we dont want to see *
#* our tmp file since it will be deleted when this script finishes.        *
