+# System clipboard integration
+#
+# This file has support for doing system clipboard copy and paste operations
+# from the command line in a generic cross-platform fashion.
+#
+# On OS X and Windows, the main system clipboard or "pasteboard" is used. On other
+# Unix-like OSes, this considers the X Windows CLIPBOARD selection to be the
+# "system clipboard", and the X Windows `xclip` command must be installed.

+# clipcopy - Copy data to clipboard
+#
+# Usage:
+#
+#  <command> | clipcopy    - copies stdin to clipboard
+#
+#  clipcopy <file>         - copies a file's contents to clipboard
