Chain trace
A jj2 file packer v0.1 (C++ version)
Coded by Overlord of J2HG

This is a simple program that will collect all neccessary information for
your jj2 level pack, and create a zip archive as a result. The example
program ctrace.exe takes two parameters. First is a starting level
filename, and the other is the name of the zip archive to be created. The
program starts with the given level, and reads the linked files i.e.
tileset, music, next level, etc, and chain traces (loops) through all found
files until there are no more unique entires to process. After that, the
file list is passed to a routine that sums all files into a zip archive
ready for redistribution. 

Included is a free source code that you may modify and/or reuse for any
purpose.
The source code files (except zip.cpp, zip.h) belong to a public domain.
