+#
+# Color certain parts of text in certain buffers based on rules.
+#
+
+#
+# Options:
+#
+# plugins.var.ruby.colorizer.buffer_regex
+# Buffers with names matching this regex are colorized. All buffers are
+# colorized if this option is empty.
+#
+# plugins.var.ruby.colorizer.rule.count
+# This is the maximum number of rules to load.
+#
+# plugins.var.ruby.colorizer.rule.X
+# X is zero or a positive integer. Rules are strings consisting of a regular
+# expression followed immediately by a slash and a Weechat color name. The
+# regular expressions are case-insensitive.
+#
+# Text matching the regular expression is colored with the given color. The
+# last match "wins" and overlapping matches are not detected.
+#
+# For example: "strelka|mongrel2/lightgreen"
+#
+
+#
+# Changelog:
+#
+# 0.1: Initial release.
