#  shgangul  7/16/04   Display the Java call for debug
#  phnguyen  7/19/04   add "./" to class path
#  phnguyen  7/31/04   more jre parsing, error if can't find java
#  shgangul  8/05/04   change opatch to oracle.opatch package
#  shgangul  8/27/04   sync up with opatch.bat to support OPATCH_PLATFORM_ID
#  phnguyen  8/04/04   Support OPATCH_PLATFORM_ID=integer
#  shgangul  8/27/04   add fallback schemes for jre/jdk
#  phnguyen  8/30/04   Print "OPatch Succeeded" if OK

#  shgangul  07/18/05  Do not pass PATH env var to OPatch JVM
#  vsriram   12/06/05  Change the permissions of .patch_storage and set umask
#  vsriram   12/13/05  Use -d inside if condition, as -e doesnot work on Solaris.
