# Description:
#       Give a list of applied patches similar in format to the showrev -p
#       command. Had to write my own because the showrev command won't take
#       a -R option.
#
# Parameters:
#       $1      - package database directory
#
# Locals used
#       arg
#       tmpStr
#
# Globals used
#       PatchNum
#       force
#
# Globals Set:
#       ObsoletedBy
#       ThisPatchFnd
#       PatchedPkgs
#       ReqdOSPatchFnd  The patch that this OS release requires was found
#
# Revision History
#       1995-08-01      Added PATCH_OBSOLETES and expanded the tests for
#                       direct instance patches since all necessary
#                       is reviewed at this time, this function also
#                       tests for obsolescence, dependencies and
#                       incompatibilities.

#       Evaluate the applied patch to be sure we aren't going to hose up 
#       any existing backout data.
#
#       If this is a progressive instance patch, here's how it is evaluated:
# prev  | curr | .nofilestosave |   OK to   |  How to verify previous
# save  | save |    exist?      | continue? |    save/no_save state
#-------+------+----------------+-----------+--------------------------
#       |      |      yes       |           | a. empty save directory
# 1 yes | yes  |----------------| continue  +--------------------------
#       |      |       no       |           | b. ! empty save directory
#-------+------+----------------+-----------+--------------------------
#       |      |      yes       | continue  | a. empty save directory
# 2 yes |  no  |----------------+-----------+--------------------------
#       |      |       no       | terminate | b. ! empty save directory
#-------+------+----------------+-----------+--------------------------
# 3  no |  no  |       no       | continue  |    empty save directory
#-------+------+----------------+-----------+--------------------------
# 4  no | yes  |       no       | terminate |    empty save directory
#-------+------+----------------+-----------+--------------------------
#
#       And the direct instance patch is evaluated as follows:
#  prev  | curr |   OK to   |  How to verify previous
#  save  | save | continue? |    save/no_save state
# -------+------+-----------+------------------------------------------
# A.  no | yes  | terminate | ! -d /var/sadm/pkg/<pkg>/save/<patch_id>
