+                         The luamplib generic package.
+
+
+This package allows typesetting of metapost natively in the TeX documents
+thanks to the LuaTeX mplib library. It only works in PDF mode.
+
+This package is developped on <http://github.com/eroux/lualatex/tree/master>.
+
+
+Installation
+------------
+
+Here are the recommended installation methods (preferred first).
+
+1. If you are using TeX Live 2008 or later, use 'tlmgr install luamplib'.
+Alternatively, try your (TeX or Linux) distribution's package management system.
+
+2. a. Grab luamplib.tds.zip on the CTAN.
+   b. Unzip it at the root of one or your TDS trees.
+   c. You may need to update some filename database after, see your TeX
+distribution's manual for details.
+
+3. a. Grab the sources from CTAN or github.
+   b. Run 'make install TEXMF=/path/to/texmf'.
+   c. See 2c.
+
+4. Try to figure it out by looking at the Makefile and comments in the sources.
+

+% Package to have metapost code typeset directly in a document with Lua\TeX .
+% \end{abstract}
+%
+% \section{Documentation}
+%
+% This packages aims at providing a simple way to typeset directly metapost code in a document with Lua\TeX . Lua\TeX\ is built with the lua \texttt{mplib} library, that runs metapost code. This package is basically a wrapper (in Lua) for the Lua \texttt{mplib} functions and some \TeX\ functions to have the output of the \texttt{mplib} functions in the pdf.
+%
+% The package need to be in PDF mode in order to output something, as PDF specials are not supported by the DVI format and tools.
+%
+% The metapost figures are put in a \TeX\ \texttt{hbox} with dimensions adjusted to the metapost code.
+%
+% The code is from the \texttt{supp-mpl.lua} and \texttt{supp-mpl.tex} files from Con\TeX t, they have been adapted to \LaTeX\ and Plain by Elie Roux. The changes are:
+%
+% \begin{itemize}
+% \item a \LaTeX\ environment
+% \item all \TeX\ macros start by \texttt{mplib}
+% \item use of the luatextra printing and module functions
+% \end{itemize}
+%
+% Using this package is easy: in Plain, type your metapost code between the macros \texttt{mplibcode} and \texttt{endmplibcode}, and in \LaTeX\ in the \texttt{mplibcode} environment.
+%
+% In order to use metapost, some \texttt{.mem} files are needed. These files must be generated with the same version of \texttt{mplib} as the version of Lua\TeX . These files names can be changed, they are by default \texttt{luatex-plain.mem} and \texttt{luatex-mpfun.mem}. If this package is to be included in a distribution, some values may have to be changed in the file \texttt{luamplib.lua}, see comments.
+%
+%
+% If your distribution does not provide valid \texttt{.mem} files (\TeX Live 2009 will be the first), you'll have to generate and install them by hand, with the script \texttt{luamplib-createmem.lua} included in this package.
+%
+% \section{Files}
+%
+% This package contains three files:
+% \begin{itemize}
+% \item \texttt{luamplib.lua} containing the lua code that calls mplib
+% \item \texttt{luamplib.sty} containing the macros for \LaTeX\ and Plain
+% \item \texttt{create-mem.lua}, a standalone mem generation script
+% \end{itemize}

+%
+% \subsection{\texttt{luamplib.lua}}
+%
+% First the \texttt{luamplib} module is registered as a Lua\TeX\ module, with some informations. Here we can't name it \texttt{mplib}, as the name is already taken.
+%
+%    \begin{macrocode}
+
+luamplib = { }
+
+luamplib.module = {
+    name          = "luamplib",
+    version       =  1.01,
+    date          = "2009/03/09",
+    description   = "Lua functions to typeset Metapost directly with MPLib.",
+    author        = "Hans Hagen, Taco Hoekwater & Elie Roux",
+    copyright     = "ConTeXt Development Team & Elie Roux",
+    license       = "CC0",
+}
+
+luatextra.provides_module(luamplib.module)
+
+%    \end{macrocode}
+% This module is a stripped down version of libraries that are used
+% by Con\TeX t.
+%    \begin{macrocode}
+
+local format, concat, abs = string.format, table.concat, math.abs
+
+%    \end{macrocode}
+% 
+% The \texttt{mem} file and the format name are hardcoded, and they can be set with \TeX\ if it's useful. The \TeX\ distributions should change these values if necessary.
+%
+%    \begin{macrocode}
+
+luamplib.currentformat = "plain"
+luamplib.currentmem = "luatex-plain.mem"
+
+local currentformat = luamplib.currentformat
+local currentmem = luamplib.currentmem
+
+function luamplib.setformat (name)
+    luamplib.currentformat = name
+end
+
+function luamplib.setmemfile(name)
+    luamplib.currentmem = name
+end
+
+%    \end{macrocode}
+%
+% We use the \texttt{kpse} library unless a finder is already defined. To find the .mem files with kpse, we have to set the \texttt{engine} environment variable to \texttt{metapost}.
+%
+%    \begin{macrocode}
+
+luamplib.finder = luamplib.finder or function(name, mode, ftype)
+    if mode == "w" then
+        return name
+    else
+        local result
+        if ftype == 'mem' then
+            local envsave = os.getenv('engine')
+            os.setenv('engine', 'metapost')
+            result = kpse.find_file(name,ftype)
+            os.setenv('engine', envsave)    
+        else
+            result = kpse.find_file(name,ftype)
+        end
+        return result
+    end
+end
+
+function luamplib.info (...)
+    luatextra.module_info('luamplib', format(...))
+end
+
+function luamplib.log (...)
+    luatextra.module_log('luamplib', format(...))
+end
+
+function luamplib.term (...)
+    luatextra.module_term('luamplib', format(...))
+end
+
+function luamplib.warning (...)
+    luatextra.module_warning('luamplib', format(...))
+end
+
+function luamplib.error (...)
+    luatextra.module_error('luamplib', format(...))
+end
+
+%    \end{macrocode}
+%
+% This is a small hack for \LaTeX . In \LaTeX\ we read the metapost code line by line, but it needs to be passed entirely to \texttt{luamplib.process}, so we simply add the lines in \texttt{luamplib.data} and at the end we call \texttt{luamplib.process} on \texttt{luamplib.data}.
+%
+%    \begin{macrocode}
+
+luamplib.data = ""
+
+function luamplib.resetdata()
+    luamplib.data = ""
+end
+
+function luamplib.addline(line)
+    luamplib.data = luamplib.data .. '\n' .. line
+end
+
+function luamplib.processlines()
+    luamplib.process(luamplib.data)
+    luamplib.resetdata()
+end
+
+
+
+%    \end{macrocode}
+%
+%
+% \begin{macro}{luamplib.load}
+%
+% This function is the one loading the metapost format we want. It uses the \texttt{luamplib.currentformat} and \texttt{luamplib.currentmem} to determine the format and the mem file to use.
+%
+% The rest of this module is not documented. More info can be found in the
+% Lua\TeX\ manual, articles in user group journals and the files that
+% ship with Con\TeX t.
