# Latexmk configuration for dissertation template
# ========================================================================
# This file works with both local builds (VimTeX, CLI) and Overleaf.
# Overleaf automatically detects and uses .latexmkrc files.
#
# Usage:
#   latexmk main.tex          -- build
#   latexmk -c main.tex       -- clean auxiliary files
#   latexmk -C main.tex       -- clean everything including PDF
# ========================================================================

# Enable shell escape (needed by some packages)

# BibLaTeX / Biber support

# Glossaries / makeglossaries support
# This rule runs makeglossaries when .glo or .acn files change
