-# Use keyboard shortcuts to copy the selection to the clipboard and to paste
-# the clipboard contents (optionally escaping all special characters).
-# Requires xsel to be installed!
-
-# Usage: put the following lines in your .Xdefaults/.Xresources:
-#   URxvt.perl-ext-common: ...,clipboard
-#   URxvt.keysym.M-c:   perl:clipboard:copy
-#   URxvt.keysym.M-v:   perl:clipboard:paste
-#   URxvt.keysym.M-C-v: perl:clipboard:paste_escaped
-
-# Options:
-#   URxvt.clipboard.autocopy: If true, PRIMARY overwrites clipboard
-
-# You can also overwrite the system commands to use for copying/pasting.
-# The default ones are:
-#   URxvt.clipboard.copycmd:  xsel -ib
-#   URxvt.clipboard.pastecmd: xsel -ob
-# If you prefer xclip, then put these lines in your .Xdefaults/.Xresources:
-#   URxvt.clipboard.copycmd:  xclip -i -selection clipboard
-#   URxvt.clipboard.pastecmd: xclip -o -selection clipboard
-# On Mac OS X, put these lines in your .Xdefaults/.Xresources:
-#   URxvt.clipboard.copycmd:  pbcopy
-#   URxvt.clipboard.pastecmd: pbpaste
-
-# The use of the functions should be self-explanatory!
