#    NAME
#      afddriverstate - front end for the Perl script that does the work.

#    DESCRIPTION
#      Purpose
#          Verify AFD installation/load/version/supported.
#
#
#    NOTES
#      This wrapper program supports only Lunix/Unix platforms.
#      Use afddriverstate.bat for Windows platforms.

# If ORA_CRS_HOME is still not right - that is, it does not
# contain AFD libraries, it means that the script is being run before it is
# instantiated with an env variable that is not right.
# We will try one last time to find a good GIHome to run from.
# This is because afddriverstate must be able to run
# before afdroot is run - the patch and install setup uses
# this script to tell if AFD is supported, and it is run
# before AFD scripts are instantiated.
# So we try and use the path we are running from, where we assume
# that this is a GI home.
if [ ! -r $ORA_CRS_HOME/lib/osds_afddriverstate.pm ] ; then
    # Take the path we are running from, which we assume is the
    # GI Home/bin and go one level up to find the GI Home.
    ORA_CRS_HOME=`dirname $0`
    # ORA_CRS_HOME now == '.' if we are running the cwd.  
    # Otherwise, if we had an absolute path, we have a real name there.
    #  so, if it == '.', just use 'pwd'.
    if [ "$ORA_CRS_HOME" = "." ] ; then

    # Following was tested on AIX, Solaris, Linux under /bin/sh.
    # Strips the ending 'bin' directory from the path name.
    # This assumes we are always running afddriverstate from a directory
    # called bin.
    # This should be a valid assumption - shiphomes always have it in
    # GIHome/bin.
    # (True to form, bourne shell on solaris is missing substitutions.)
    # The following expr command will return everything from the left up to 
    #   the final '/bin'.  It has been tested with /1/2/3/4/bin and 
    #   /1/2bin/3/bin, and appears to work well.
    # In ADE, if run from usm/bin, with no ORACLE_HOME or ORA_CRS_HOME
    #  set in the env, this will look in usm/lib for the 
    #  tools driver, but that is no different from current state.
