+dbar, (c) 2007 by Robert Manea
+==============================
+
+dbar is an application that generates semi graphical progress meters,
+from some values you supply to it.
+
+See the usage examples for a description of the expacted input format.
+
+Options:
+--------
+
+     -max :  Value to be considered 100%   (default: 100)
+     -min :  Value to be considered   0%   (default: 0  )
+     -w   :  Number of charcaters to be 
+             considered 100% in the meter  (default: 25 )
+     -s   :  Symbol represeting the 
+             percentage value in the meter (default: =  )
+     -l   :  label to be prepended to 
+             the bar                       (default: '' )
+     -nonl:  no new line, don't put 
+             '\n' at the end of the bar    (default: do print '\n')
+
+dbar lets you define static 0% and 100% marks with the '-min' and '-max'
+options or you can provide these marks dynamically at runtime.  Static
+and dynamic marks can be mixed, in this case the value specified at
+runtime will have a higher priority.
+
+You can specify ranges of numbers, negative, positive or ranges with a
+negative min value and positive max value.
+
+All numbers are treated as double precision floating point, i.e. the
+input is NOT limited to integers.
+
+
+Usage examples:
+
+ 1) Static 0% and 100% mark or single value input:
+
+   echo 25 | dbar -m 100 -l Sometext
+
+   Output: Sometext  25% [======                   ]
+
+ 2) If your 100% mark changes dynamically or 2-values input:
+
+   echo "50 150" | dbar
+         ^   ^
+         |   |__ max. value
+         |
+         |__ value to display
+
+   Output: 33% [========                 ]
+
+ 3) If your value range is not between [0, maxval] or 3-values input:
+
+   echo "50 -25 150" | dbar
+         ^   ^  ^
+         |   |  |__ max. value 100% mark
+         |   |
+         |   |_____ min. value 0% mark
+         |
+         |________ value to display
+
+   Output: 43% [===========              ]
+
+
+ 4) Multiple runs:
+
+   for i in 2 20 50 75 80; do echo $i; sleep 1; done | dbar | dzen2
+
+   Output: Find out yourself.
