Any ZIP software utility supporting the compression method DEFLATE can be used to create a Pack file. Simply, create the ZIP file and rename it to *.pack.

7-Zip

The compression tool 7-Zip supports command line calls and can be used in generation scripts like gen_pack.sh for automated Pack file creation (and verification with PackChk).

Installing on Linux

Use your package manager to install 7-Zip. On a Ubuntu machine, use:

$ sudo apt-get install p7zip-full

Installing on Windows

In the download section of 7-Zip, download the appropriate installer for your Windows system. Use defaults for your installation.

gen_pack.sh assumes that your installation path is "C:\Program Files\7-Zip". If you choose to use another location, please adapt the path in the Bash script.
