## README

Leex is a lexical analyzer generator for Erlang. It allows you to
tokenize a textual input stream so that it can be grammatically
analyzed and processed by yecc. It is NOT a part of OTP at this point.

v0.3
----
Added options to pushback characters into the input stream.

Can now handle full unicode character sets in both input file and
generated scanner. Of course i/o system can't generate such an input
file yet.

Enforce headings for all sections of .xrl file.

Added verbose flag to control printing of parsing information.

Fixed bug with completely empty erlang code section.

v0.2
----
Added includefile option. Search for include file in current directory
or leex/include lib dir.

Restored text file version of documentation until I edoc and I are in
agreement.

Upgraded erlang_scan.xrl to full erlang tokeniser.

Now use line number of token start.


Thanks to Sbastien Arnaud who did the first packaging of leex for git.
