pkgGen is a perl script that parses the output from logGen and copies the files to a fake root directory. You can use this tree to build a package using packagemaker, iceberg or some other packaging tool.

The script comes in an installer package that places it in ``/usr/local/sbin`:



# pkgGen v1
# Zack Smith
# Based on a script originally created by Geoff Franks (Buy him the Beer)
# Hauptman-Woodward Medical Research Institute
# This script takes two parameters. The first is the path to the 
# LogGen > log file. The second is the folder which you would like to 
# create your Root directory for the PKG installer to base from. This folder 
# MUST NOT exist, or the script will fail. 
# It parses the log file, regenerating the drectory structure of added files 
# and directories, preserving permissions, modification times, and resource 
# forks as tightly as possible. IMPORTANT: To preserve all permissions, run this
# with root level permissions. 
# More to come later...
