+Leg 0.1.2
+=========
+
+This is a release of Leg, a Lua library exporting a complete Lua 5.1 grammar 
+and a small API for user manipulation.
+
+
+Dependencies
+------------
+
+* You need, understandably, to have Lua 5.1 up and running to be able to use
+this library :)
+
+* Also, Leg uses LPeg 0.7 extensively for pattern matching, so LPeg is 
+expected be installed. You can get LPeg at 
+
+http://www.inf.puc-rio.br/~roberto/lpeg.html
+
+
+Basic Installation
+------------------
+
+There are three ways to install Leg:
+
+* `make` or `make leg`
+
+  A directory `leg` will be created in your working directory, with the 
+  source files inside. Just put it in a LUA_PATH-visible place and you're 
+  ready to go.
+
+* `make install`
+
+  If you have the proper permissions, you can run `make install` and the 
+  `leg` directory with the source files will be put in a specific path. 
+  Tweak Makefile's LUA_LIB variable to indicate the appropriate path for your 
+  system; Makefile ships with it set to /usr/local/share/lua/5.1 .
+
+* by hand
+
+  If you don't have or don't want to use `make`, you can just put all the 
+  files in `src` inside a directory called `leg`, and put that directory in 
+  your LUA_PATH.
+
+  Read the Lua Reference Manual for the LUA_PATH and the LUA_CPATH syntax
+  (http://www.lua.org/manual/5.1/manual.html#pdf-package.path).

+New Stuff

+
+
+Work to do
+----------
+
+* Improve error checking: currently it is bolted on and not extensible, and 
+  different patterns react differently to mismatching: scanner.STRING throws 
+  an error when a mismatch happens, but some errors simply return false and an
+  error message. I don't know a good way to handle this.
+
+* A better API for grammar extensions. The current one is very ad hoc, and
+  requires some fine tuning to make sure it works correctly. Metalua's API 
+  seems interesting, and was originally based on Parsec. Investigation is 
+  under way.
+
+* More thorough testing.

+========
+
+API
+===
+
+* grammar.lua received two new utility functions: anyOf and listOf
+
+Bugs
+====
+
+* adding scanner's keywords e symbols to parser's rules ended up altering 
+  scanner.keywords and scanner.symbols as well; using grammar.complete instead
+  of grammar.apply does the trick.
+
+Documentation
+=============
+
+* changes in the documentation generator made the new docs slightly different;
+  no big conceptual change.
+
+* an improved README file
+
+* a COPYRIGHT file with Leg's license
+
+* and this release file
