# Re-create a Solaris package installation file from it's installed

#
# Limitations:
#   This script will only capture files that have entires in the 
#   /var/sadm/install/contents file.  It will not capture other files such
#   as config files that were added for the package later.  It will also 
#   not capture any pre or post install scripts that may have been used
#   when the package was originally installed.
# 
#   The file ownerships and permissions in the new package are will be the
#   same as the actual file ownerships and permissions, not what they were
#   when the file was originally installed.
