+# This makes defining styles a bit simpler by using a single `+' as a
+# special token that allows to append a context name to the previously
+# used context name. Like this:
+#
+#   zstyle+ ':foo:bar' style1 value1 \
+#         + ':baz'     style2 value2 \
+#         + ':frob'    style3 value3
+#
+# This defines style1 with value1 for the context :foo:bar as usual.
+# But it also defines styles2 with value2 for the context :foo:bar:baz
+# and style3 with value3 for :foo:bar:frob.
+# Of course, any of the sub-contexts after the plus signs may be 
+# empty strings to re-use the previous context unchanged.
+#
+# If you don't want to change all your calls to `zstyle' to use
+# `zstyle+' you can use an alias `alias zstyle=zstyle+' and make sure
+# the completion functions are autoloaded without alias expansion (the
+# -U option to the autoload builtin). The completion system normally
+# loads its functions with without alias expansion.
