+Options:
+  --source-base PATH     Base directory where notes root begins (default: \$HOME)
+  --notes-root PATH      Path from base to notes root (default: notes/courses)
+  --section-dir PATH     Relative path under notes root to export (default: current directory)
+  
+  --share-rel PATH       Relative path (from section-dir) to a shared _share directory (e.g. ../_share)
+                         If provided, its contents will be copied to the DEST/_share folder (as a sibling)
+
+  --debug                Print resolved paths and stop before exporting
+  --help                 Show this help message
+
+
+Behavior:
+  - .org files are exported only if newer than corresponding .html files.
+  - Shared assets from both --share-rel and section-local _share/ are merged into the destination.
+  - Symlinks are preserved; .bak, .log, and dotfiles are excluded from rsync copies.
+
+Examples:
+  cd ~/notes/courses/business/music_money_makeover
+  $0 --debug
+
+  $0 \\
+    --source-base ~/notes \\
+    --notes-root notes/courses \\
