+echo -e ' High Beam Highlighter 
+- a trial to create a very generic modifyable 
+syntax highlighter.
+
+Example rules: ( ~/.highbeamrc )
+--------------------
+RULES=( 
+    "[0-9]"      "$c" # Show numbers with Cyan color. NOTE: since the colors are represented with numbers, having this later in the rules will break coloring!
+    "$USER[ ]\+$USER"  "$BC$K" # Use quotes to have rules with spaces. This colors the "ls -la" usernames. background cyan, black text
+    status       "$g" # simple word matching, coloring green
+    "^d[^ ]*"    "$G" # color words at the beginning of line, starting with d.  color bright green
+    "q.\{0,3\}r" "$Y" # q*r with maximum 3 characters in between. color bright yellow
+)
+--------------------
+Rules can be also exressed as a space separated list variable:
+export HB_RULES='\''"[0-9]" "$C" "g" "$Y"'\''
+   HB_RULES are appended to other rules
+
+Bright colors:  $R $G $B $Y $M $C $W $K
+Dark colors:    $r $g $b $y $m $c $w $k
+Modify to bright version by prefixing with $H  (e.g. $H$g)
+Background colors: $BR $BG $BB $BY $BC $BM $BW 
+Underline: $U
+
+Usage:   highbeam [-c] [-h] [-f config]
+   -c    Be case sensitive
+   -D    Print current rules, not the input
+   -h    Help
+   -f    Define config file (default ~/.highbeamrc)
+   -r    Define rules with a string, replaces the other rules
+            -r '\''"land[^[:space:]]\+" "$G" "sky" "$B"'\''
