# Drag and drop plugin for Clifm
# Written by L. Abramovich
# License: GPL2+

# Description:
# With no arguments, it opens a window to drop files; otherwise, files
# passed as arguments are send to the Dragon window to be dragged onto
# somewhere else.
#
# Files dropped remotely are first downloaded via cURL into the CWD and
# then sent to the SelBox, whereas files dropped locally are directly
# sent to the SelBox.

# Dependencies:
# dragon (https://github.com/mwh/dragon), grep, sed, curl, xargs, tr
