This directory contains the source code for a simple Eiffel scanner.
It uses Gelex to generate class EIFFEL_SCANNER.

Class EIFFEL_SCANNER has three creation procedures. `make' just creates
a scanner. `execute' creates a scanner and scans the files given in the 
command line, one by one. `benchmark' expects the command line to be made
up of a number 'nb' followed by a filename. It creates a scanner and scans
'nb' times the file given as second argument.

Note: This Eiffel scanner is just a simple example. It is not intended
to be perfect or to follow any Eiffel syntax standard. Moreover, it does
not generate any output.

To compile this example:

1. Use the script 'make scanner' to generate class EIFFEL_SCANNER
   if necessary.
2. Choose either `execute' or `benchmark' as the creation procedure of
   the root class EIFFEL_SCANNER in your Ace file (ISE Eiffel: ise.ace,
   Halstenbach: hact.ace), your ESD file (Visual Eiffel: ve.esd) or
   your command line (SmallEiffel).
3. Use your favorite Eiffel compiler to compile the Eiffel system using
   the provided Ace file (ISE Eiffel: ise.ace, Halstenbach: hact.ace),
   ESD file (Visual Eiffel: ve.esd) or loadpath file (SmallEiffel:
   loadpath.se). If you have GNU make, you can alternatively type:
   'make ise', 'make hact', 'make ve' or 'make se'.
4. Execute the Eiffel scanner using
       eiffel_scanner filename1 ...
   if you selected `execute' as creation procedure, or
       eiffel_scanner nb filename
   if you selected `benchmark', where `filename', `filename1', etc. are
   filenames containing Eiffel classes and `nb' is an integer.
