+# Less With Style
+
+I was using `less` the other day to look at a log file. The log file was
+filled with ANSI color escape sequences which made it pretty painful to
+read. I was stuck looking at a white, unparsed log file instead of a
+colorful, stylish one.
+
+The `-R` flag fixes this. It tells `less` to display the ANSI color escape
+sequences as colors rather than the caret notation.
+
+The tradeoff is that `less` has _less_ control over the overall display of
+the screen. This may result in some buggy display behavior, but not
+necessarily.
