+# Startdate: 2021-01-29 15:35
+# Purpose: generate symlink forest of a directory path
+# methodology:
+#    1. read exif data first, YYYY/MM
+#    2. use timestamp of file, and log warnings
+# Usage:
+#    ./generate.py -i /mnt/bgstack15/Backups/bgstack15/Images/Photos/camera/2018/ -o /mnt/public/www/gallery/my2018 -n -d2 -x 'October' -s --nr
