# Description:
# by using utility "qpakman",
# creating Quake2 PAK-files at output directory (root of project for later use by GitHub Actions),
# from dirs/files of each directory from user provided list
# 2020-09 by Amok[MEn]

# Assuming that this script is running from project root directory

# This path would be part of absolute path, so here should not be any prefix dot and "/"
# Just "qpakman" --> would search tool at the same path where script was run from
PAK_CREATION_TOOL_PATH="qpakman"

# Each dir here would become PAK-file
# HARDCODE! If change this list - change also GitHub Actions workflow!
LIST_SOURCE_DIRS_NAMES="pak96_env pak97_models pak98_pics pak99_textures pak97_models_bright pak95_v_models"

# Here would be all created PAK-files

# Log file name
