# datedist.pl v0.2.0 docs {{{
#
# datedist.pl is a file distribution script written by Roy Sigurd Karlsbakk
# <roy@karlsbakk.net>. I wrote it to distribute a few thousand files in a
# directory so that they were all placed under a directory hiearchy like
# YYYYY/MM/DD to allow for me to find them later. I typically use this after a
# manual import of the pics, before importing those into Lightroom. 
#
# 2013-01-30: Added --exif for using exiftool to extract shoot date instead of
# file dates, which may be different than shoot date.
#
# 2013-01-31:
#  - Changed license to AGPL 3.0.
#  - Added more documentation.
#  - Added check to see if destination file exists to avoid overwriting existing
#    stuff.
#  - Added new option --force to forcibly overwrite existing files.
#  - Added new option --dest-dir to allow other destination dir than current dir
#  - Updated to version 0.1.2
#
# 2013-05-21:
#  - Better help thanks to <malinkh@gmail.com>
#  - Updated to version 0.1.3
#
# 2014-02-17:
#  - Code cleanup
#  - Added --version
#  - Updated to version 0.1.4
#
# 2016-06-13:
#  - Changed to make --exif default
#
# 2016-06-14:
#  - Changed old --move-corresponding-(something) to --mcf=ext,ext2 etc.
#    Compatibility with old syntax is retained.
#  - Version changed to 0.9.9
#  - More testing to be done
#
# 2018-01-18:
#  - Removed dependencies on Time::Format and Image::ExifTool. The former is
#    removed and the code juse uses localtime(). The latter is used if present.
#    Also removed Dat::Dumper, since it wasn't in active use.
#
# 2023-10-07:
#  - Added hashing support in case of conflicts. So far most for show and all
#    it does is to check MD5 hash and then tell you if the files match or not. I'm just
#    tired, that's all...
