+# Each line of the theme file describes a token type and how this token type
+# should be colored (highlighted).  The first word on each line is the name
+# of the token type. After the name of the token type at least one white space
+# character must follow, and then a text and background color
+# for the highlighting must be specified, separated by a comma.  No spaces
+# are allowed inside color definition (that is, color definition is considered
+# a single word, despite a possible comma).
+#
+# Background color can be omitted (in which case default background color
+# of the terminal will be used).  If you are omitting the background color,
+# a comma may be omitted also.  Likewise, a text color can be omitted,
+# but comma must be present in this case.
