drefile: an automatic, chronological file organizer
---------------------------------------------------
Every few minutes drefile copies all files on your Desktop to a folder
such as ~/Documents/2009-06-June/26-Friday, prepending a timestamp
(like 20090626.1310) to the filename.

Use
---
1. Put files on your Desktop, and in a few minutes they will be 'drefiled'
2. Use the 'Today' alias on your Desktop to go to today's folder
3. Type 'dday' to go to today's directory
4. Type 'dmonth' to go to this month's directory
5. Type 'drefile file' to manually timestamp + move a file

Install
-------
1. `sudo port install osxutils`
2. `sudo gem install open4`
3. copy the 3 files below to ~/.bin (or whatever, in your path)
4. `chmod +x` the 3 files
5. `crontab -e` this (as your user):

# drefile desktop every 5 minutes (on the 5)
0,5,10,15,20,25,30,35,40,45,50,55 * * * * ~/.bin/drefile >> /Users/luke/.bin/drefile_cron.log

# drefile desktop once/day (at 5am)
* 5 * * * ~/.bin/drefile >> /Users/luke/.bin/drefile_cron.log
