# Scan for wlroots and x11 clipboard events and synchronize text strings.

# clipnotify https://github.com/cdown/clipnotify (xfixes clipboard events)
# wl-clipboard https://github.com/bugaevc/wl-clipboard
# xclip https://github.com/astrand/xclip
# non-text TARGET/mimetype negotiation requires a more complicated protocol
# bridge than what xclip and wl-clipboard can be expected to provide.
# To see the scope of the problem for a given selection:
# xclip -t TARGETS -o
# wl-paste -l
set -e
set -x # debug
#PS4='+ $(sleep .1)' # debug
