# commits.sh - Generate dependency version report for LessUI
#
# This script produces a comprehensive list of git commit information for:
# - Main LessUI repo
# - Toolchains (cross-compilation environments)
# - libretro-common (shared libretro code)
# - Platform-specific third-party dependencies (DinguxCommander, SDL, etc.)
# - Libretro cores (emulator implementations)
#
# Output format: NAME          HASH      DATE        USER/REPO
