## INFO
# This is a very simple script designed to be used when using the email client
# mutt remotely. It copies attachments to a web accessible folder and tells you
# where to view them.
#
# More details are available at http://puzzling.org/logs/thoughts/2010/May/6/mutt-attachments

# if you want to override OUTPUTDIR and VIEWINGDIR edit them here or create a
# ~/.copy-to-dir # file that looks like:
# OUTPUTDIR=someotherdir
# VIEWINGDIR=someother URI

# You can also optionally specify a location to rsync attachments to,
# RSYNCOUTPUTDIR=host:dir
# You'll probably want a passphraseless key for this and NO DELETION of rsynced
# attachments will take place.

### Extension
# use short generated file name

OUTPUTDIR=$HOME/public_html/attachments
VIEWINGDIR=https://ssl.meutel.net/~meutel/attachments
