# Program: saveodms
# Purpose: save the history, product, and lpp databases for future use.
# The saved vpd can be restored by restodms
#
# Usage: saveodms [-s] [-Z] {[savedir] | -f [savefile]}
# where: savedir is the directory to save the vpd tree in.
# default value: orig
# e.g. saveodms myvpd causes the vpd to get
# save under /u/myvpd.odm
# use: restore myvpd to restore.
# -Z indicates just to return the size needed for this.
# -s indicates save the short version of the odms.
# Doesn't save inventory part.
# -f indicates to save odm to a file instead of
# a directory.
# savefile is the file name to save odms into.
# default value: orig
# e.g. saveodms -f myvpd causes the vpd to
# get save as file /u/myvpd.odm.bff.Z
# use: restore -f myvpd to restore.
#
#
# Notes for directory saves:
# 1. It makes sure that we have enough space in /u to succeed.
# 2. Time of save operation is left in the save directory in the
# file timestamp.
# 3. If the savedir exists, it is moved to savedir.old
# Notes for directory saves:
# 1. It makes sure that we have enough space in /u to succeed.
# 2. If the savefile exists, it is moved to savefile.old
