#  Script:  $CDROM_DIR/CDINSTAL
#
#         * CDINSTAL should be in the root dir of the CDROM ($CDROM_DIR).
#         * CDINSTAL assumes there is the following file structure:
#
#           $CDROM_DIR/:
#            AIX41          COMMON         SCO32          SOL25 
#            CDINSTAL       HPUX905        SCO5           SUN413
#            IRIX           SOL24
#
#           $CDROM_DIR/<os name>/:
#            ADMIN.TXT     EMD.TXT       INFORMIX.TXT  ODBC.TXT      RENLD.TXT
#            ADMIN.Z       EMD.Z         INFORMIX.Z    ODBC.Z        RENLD.Z
#            COMMON.TXT    EVENTS.TXT    INSTALL.TXT   PEP.TXT
#            COMMON.Z      EVENTS.Z      INSTALL.Z     PEP.Z
#
#            (Note that due to the limitations of some OSes, all these 
#             components may not exist).
#
#         * CDINSTAL and enl_xinstall require installations from tape
#           to be extracted (creating a directory structure like above)
#           before they are invoked.
#
# 'CDINSTAL' does the following:
#  1) auto-detects the local host's OS 
#  2) asks to archive any pre-2.0 Enlighten configuration files
#  3) prompts for the local installation directory 
#  4) stores that directory pathname into /etc/enlighten
#  5) cp's the necessary applications to the installation directory
#  6) execs the installation program (enl_xinstall)
#
#
#

#
# Be anal. For security purposes any file or directory created 
# by the execution of this script should have all permission 
# on group and other turned off.
