# LUCA POST-CHECKOUT GIT HOOK

# =============================================================================

# It ensures that CLI tools are synchronized with the Lucafile specification

15+
# 1 = branch checkout (git checkout <branch>, git switch <branch>)

# 0 = file checkout (git checkout -- <file>)
17+
