+#!/bin/zsh -f
+
+# A little zsh sticky-note ("post-it") application.  Sticky notes are
+# stored in the file named by the STICKYFILE variable (defaults to
+# $HOME/.zsticky).  The number of notes stored is STICKYSIZE (1000).
+#
+# May be bound as a widget:
+#    zle -N sticky-note
+# And/or run as a command:
+#    sticky-note
+#    sticky-note -b
+#    sticky-note -l ...
+# With the -l option, lists previous sticky notes.  Most options of the
+# "fc -l" command are supported, for selecting which notes to display.
+# The -b option is like "zed -b": installs keymaps/bindings only.
+#
+# Otherwise invokes the line editor with the previous notes available
+# as an editor history.  Two quick taps on the return/enter key finish
+# the note, or you can use use ^X^W as usual (ZZ in vicmd mode).
+
+# I encourage all you creative people to contribute enhancements ...
+# no-prize for the first person to put the most recent sticky note in
+# his PS1 string.
