+/**
+ * [[config-options]]
+ * User Configuration file
+ * -----------------------
+ * You can permanently set an option by putting it in the `~/.tig` file.
+ * The file consists of a series of 'commands'. Each
+ * line of the file may contain only one command.
+ *
+ * The hash mark ('#'), or semi-colon (';') is used as a 'comment' character.
+ * All text after the comment character to the end of the line is ignored.
+ * You can use comments to annotate your initialization file.
+ *
+ * Some sample options:
+ *
+ * ==========================================================================
+ * # Diff colors
+ * color diff-header yellow default
+ * color diff-index blue default
+ * color diff-chunk magenta default
+ * # UI colors
+ * color title-blur white blue
+ * color title-focus white blue bold
+ * ==========================================================================
+ *
+ * [[color-options]]
+ * Color options
+ * ~~~~~~~~~~~~~
+ * Color options control highlighting and the user interface styles.
+ * If your terminal supports color, these commands can be used to assign
+ * foreground/backgound combinations to certain areas. Optionally, an
+ * attribute can be given as the last parameter. The syntax is:
+ *
+ * [verse]
+ * ..........................................................................
+ * *color* 'area' 'fgcolor' 'bgcolor' '[attributes]'
+ * ..........................................................................
+ *
+ * Valid colors include: *white*, *black*, *green*, *magenta*, *blue*, *cyan*,
+ * *yellow*, *red*, *default*. Use *default* to refer to the default terminal
+ * colors.
