#=== HELP START ===
# convert-md-tree.sh – Recursive Markdown → HTML conversion (Pandoc)
#
# Usage:
# ./convert-md-tree.sh [options] <source_dir> <dest_dir>
#
# Options:
# -n, --dry-run Show what would be done without converting
# -p, --pandoc-args <string> Extra arguments passed to pandoc (e.g. "-t html5")
# -h, --help Show this help message
#
# Arguments:
# <source_dir> Root directory containing .md files
# <dest_dir> Destination directory for the HTML output
#
# Behaviour:
# • Preserves the directory structure in the destination.
# • Creates required sub-directories automatically.
# • Emits clear errors for missing programs or invalid parameters.
