Description:
Example of a lexical analyzer for Eiffel.

If not previously built and stored, a stored lexical analyzer
object is created according to regular expressions described by the
file `eiffel_regular' and stored in `eiffel_lex' for doing lexical
analysis of Eiffel code.  (This may take a few moments.)  This object is
then used to analyze the file named by the argument.  Once the analyzer
has been built, subsequent calls will be much faster.

See the "Introduction to the Lexical Library" chapter of EIFFEL: THE
LIBRARIES for more information.
