pretty [options] <Class_names> ...

Command `pretty' is the SmallEiffel Pretty Printer for Eiffel 
source files. For all classes given as arguments, pretty
looks for the corresponding file using the same algorithm as
command `finder'. All the corresponding files are reprinted
in a `pretty' way.

For example, if you are allowed to write the corresponding 
file, you can reprints the source file of class HELLO_WORLD
using command :

   pretty hello_world

There are four modes of pretty printing -zen, -default, -end
and -parano mode. Only one mode can be selected and mode 
-default is the default mode.

1- Options for pretty printing -

-zen : The less you can print. Pseudo variable `Current' is 
   never printed (unless it is necessary). No end mark comment
   for routines. No end comments for constructs (if, inspect, 
   debug, ...). Very compact printing.

-default : the default mode. Don't change printing of pseudo
   variable `Current' (if Current is in the input, Current is
   in the output). Print end comment of routines.
   Don't print end comments for constructs (if, inspect, 
   debug, ...).
       
-end : Same printing as previous mode but print ends of all 
   constructs (if, inspect, debug, ...).

-parano : Same printing as previous mode but prints `Current' 
   everywhere you can.

2- Security and BackUp file -

For the security of sources files, a backup file is created 
before writting the new file (system or command `pretty' may
crash during printing of the new file).
The backup file name is "foo.bak" when source file name is 
"foo.e". Backup file is written in the same directory as 
source file. 
If an old backup file already exists before pretty printing, 
command `pretty' exit with an error message.
To be sure that the pretty printing is well done, the output 
file is parsed again.
Even if second parsing gives no errors, backup file is NOT 
removed. Thus you can recompile your Eiffel code to check
new file before removing backup file by yourself.
