+\startsubsection[title=Running code]

+        {path=runpath}
+        {go to given path before execution}

+        {run a script or program and time its run (external)}
+\stopoptions
+
+Specifying both \type {--iftouched} and \type {--ifchanged} means both are

+come before one of the next options:
+
+\startoptions
+    \option
+        {script}
+        {run an mtx script (where \LUA\ is the preferred method); it has the
+         sub||options \typ {--nofiledatabase}, \typ {--autogenerate}, \type

+\stopoptions
+
+Since scripts potentially have their own options, any options intended for
+\sMTXRUN\ itself have to come {\it before} the option that specifies the script
+to run, and options for the script itself have to come {\it after} the option
+that gives the script name. This is especially true when using \type {--script},
+so it is important to check the order of your options.
+
+Of the four above options, \type {--script} is the most important one, since that
+is the one that finds and executes the \LUA\ \sMTXRUN\ scripts provided by the
+distribution. With \typ {--nofiledatabase}, it will not attempt to resolve any
+file names (which means you need either a local script or a full path name). On
+the opposite side, when you also provide \typ {--autogenerate}, it will not only
+attempt to resolve the file name, it will also regenerate the database if it
+cannot find the script on the first try. In a future version of \CONTEXT, the
+\type {--load} and \type {--save} will allow you to save|/|restore the current
+command line in a file for reuse.
+
+The shell return value of \sMTXRUN\ indicates whether the script was found. When
+you specify something like \type {--script base}, \sMTXRUN\ actually searches
+for \type {mtx-base.lua}, \type {mtx-bases.lua}, \type {mtx-t-base.lua}, \type
+{mtx-t-bases.lua}, and \type {base.lua}, in that order. The
+distribution||supplied scripts normally use \type {mtx-<name>.lua} as template.
+The template names with \type {mtx-t-} prefix is reserved for third||party
+scripts, and \type {<name>.lua} is just a last-ditch effort if nothing else
+works. Scripts are looked for in the local path, and in whatever directories the
+configuration variable \type {LUAINPUTS} points to.
+
+The \type {--execute} options exists mostly for the non||\LUA\ {\MKII} scripts
+that still exist in the distribution. It will try to find a matching interpreter
+for non||\LUA\ scripts, and it is aware of a number of distribution||supplied
+scripts so that if you specify \type {--execute texexec}, it knows that what you
+really want to execute is \type {ruby texexec.rb}. Support is present for \RUBY\
+(\type {.rb}, \LUA\ (\type {.lua}), python (\type {.py}) and \PERL\ (\type {.pl})
+scripts (tested in that order). File resolving uses \type {TEXMFSCRIPTS} from the
+configuration. The shell return value of \sMTXRUN\ indicates whether the script
+was found and executed.
+
+The \type {--internal} option uses the file search method of \type {--execute},
+but then assumes this is a \LUA\ script and executes it internally like \type
+{--script}. This is useful if you have a \LUA\ script in an odd location.
+
+The last of the four options, \type {--direct}, directly executes an external
+program. You need to give the full path for binaries not in the current shell
+\type {PATH}, because no searching is done at all. The shell return value of
+\sMTXRUN\ in this case is a boolean based on the return value of
+\type {os.exec()}.
+
+It is also possible to execute bare \LUA\ code directly:
+
+\startoptions
+    \option
+        {evaluate}
+        {run code passed on the command-line (between quotes)}
+\stopoptions
+
+\stopsubsection
+
+\startsubsection[title=Options for maintenance of \sMTXRUN\ itself]
+
+None of these are advertised. Normally developers should be the only ones needing
+them, but if you made a change to one of the distributed libraries (maybe because
+of a beta bug), you may need to run \type {--selfmerge} and \type {--selfupdate}.
+
+\startoptions

+\startsubsection[title=Creating stubs]
+
+Stubs are little shortcuts that live in some binaries directory. For example, the

+
+\starttyping
+#!/bin/sh
+mtxrun --script context "$@"
+\stoptyping
+
+Apart from the \sCONTEXT\ command itself (which is provided by the distribution),
+use of stubs is discouraged. Still, the \sMTXRUN\ options are there because
+sometimes existing workflows depend on executable tool names like \type
+{ctxtools}.

+\startsubsection[title=Remaining options]
+
+The remaining options are hard to group into a subcategory. These are the
+advertised options:

+\startoptions
+    \option

+        {show current operating system, processor, et cetera}
+    \option

+\stopsubsection
+
+\startsubsection[title=Known scripts]
+
+When you run \type {mtxrun --scripts}, it will output a list of \quote {known}
+scripts. The definition of \quote {known} is important here: the list comprises
+the scripts that are present in the same directory as \type {mtx-context.lua}
+that do not have an extra hyphen in the name (like \type {mtx-t-...}scripts would
+have). In a normal installation, this means it \quote {knows} almost all the
+scripts that are distributed with \CONTEXT. Note: it skips over any files from
+the distribution that do have an extra hyphen, like the \type {mtx-server}
+support scripts.
+
+Since this section is about \sMTXRUN, I'll just present the list of the scripts
+that are \quote {known} in the current \CONTEXT\ beta as output by \sMTXRUN\
+itself, and not get into detail about all of the script functionality (they all
+have \type {--help} options if you want to find out more). Where we still felt the
+need to explain something, there is an extra bit of text in italics.

+\startsubsection[title=Writing your own]
+
+A well|-|written script has some required internal structure. It should start with
+a module definition block. This gives some information about the module, but more
+importantly, it prevents double|-|loading.
+
+Here is an example:
+
+\starttyping
+if not modules then modules = { } end
+
+modules ['mtx-envtest'] = {
+    version   = 0.100,
+    comment   = "companion to mtxrun.lua",
+    author    = "Taco Hoekwater",
+    copyright = "Taco Hoekwater",
+    license   = "bsd"
+}
+\stoptyping
+
+Next up is a variable containing the help information. The help information is actually
+a bit of \XML\ stored in \LUA\ string. In the full example listing at the end of this
+article, you can see what the internal structure is supposed to be like.
+
+\starttyping
+local helpinfo = [[
+<?xml version="1.0"?>
+<application>
+  ....
+</application>
+]]
+\stoptyping
+
+And this help information is then used to create an instance of an \type
+{application} table.
+
+\starttyping
+local application = logs.application {
+    name     = "envtest",
+    banner   = "Mtxrun environment demo",
+    helpinfo = helpinfo,
+}
+\stoptyping
+
+After this call, the \type {application} table contains (amongst some other
+things) three functions that are very useful:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {identify()}
+    {Prints out a banner identifying the current script to the user.}
+\mtxrunenv
+    {report(str)}
+    {For printing information to the terminal with the script name as prefix.}
+\mtxrunenv
+    {export()}
+    {Prints the \type {helpinfo} to the terminal, so it can easily be used for
+     documentation purposes.}
+\stopmtxrunenvironment
+
+Next up, it is good to define your scripts' functionality in functions in a
+private table. This prevents namespace pollution, and looks like this:
+
+\starttyping
+scripts          = scripts         or { }
+scripts.envtest  = scripts.envtest or { }
+
+function scripts.envtest.runtest()
+    application.report("script name is " .. environment.ownname)
+end
+\stoptyping
+
+An finally, identify the current script, followed by handling the provided
+options (usually with an \type {if}||\type {else} statement).
+
+\starttyping
+if environment.argument("exporthelp") then
+   application.export()
+elseif environment.argument('test') then
+   scripts.envtest.runtest()
+else
+    application.help()
+end
+\stoptyping
+
+\stopsubsection
+
+\startsubsection[title=Script environment]
+
+\sMTXRUN\ includes lots of the internal \LUA\ helper libraries from \CONTEXT. We
+actually maintains a version of the script without all those libraries included,
+and before every (beta) \CONTEXT\ release, an amalgamated version of \sMTXRUN\ is
+added to the distribution. In the merging process, most all comments are stripped
+from the embedded libraries, so if you want to know details, it is better to look
+in the original \LUA\ source file.
+
+Inside \sMTXRUN, the full list of embedded libraries can be queried via the array
+\type {own.libs}:

+
+In fact, the \LUA\ table \type {own} contains some other useful stuff like the
+script's actual disk name and location (\type {own.name} and \type {own.path})
+and some internal variables like a list of all the locations it searches for its
+embedded libraries (\type {own.list}), which is used by the \type {--selfmerge}
+option and also allows the non||amalgamated version to run (since otherwise \type
+{--selfmerge} could not be bootstrapped).
+
+\sMTXRUN\ offers a programming environment that makes it easy to write \LUA\ a
+scripts. The most important element of that environment is a \LUA\ table that is
+conveniently called \type {environment} (\type {util-env} does the actual work of
+setting that up).
+
+The bulk of \type {environment} consists of functions and variables that deal
+with the command||line given by the user as \sMTXRUN\ does quite a bit of work on
+the given command||line. The goal is to safely tuck all the given options into
+the \type {arguments} and \type {files} tables. This work is done by two
+functions called \type {initializearguments()} and \type {splitarguments()}.
+These functions are part of the \type{environment} table, but you should not need
+them as they have been called already once control is passed on to your script.
+
+\startmtxrunenvironment
+\mtxrunenv
+    {arguments}
+    {These are the processed options to the current script. The keys are option
+     names (without the leading dashes) and the value is either \type {true} or a
+     string with one level of shell quotes removed.}
+\mtxrunenv
+    {files}
+    {This array holds all the non||option arguments to the current script.
+     Typically, those are supposed to be files, but they could be any text,
+     really.}
+\mtxrunenv
+    {getargument(name,partial)}
+    {Queries the \type {arguments} table using a function. Its main reason for
+     existence is the \type {partial} argument, which allows scripts to accept
+     shortened command||line options (alias: \type {argument()}).}
+\mtxrunenv
+    {setargument(name,value)}
+    {Sets a value in the \type {arguments} table. This can be useful in
+     complicated scripts with default options.}
+\stopmtxrunenvironment
+
+In case you need access to the full command||line, there are some possibilities:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {arguments_after}
+    {These are the unquoted but otherwise unprocessed arguments to your script as
+     an array.}
+\mtxrunenv
+    {arguments_before}
+    {These are the unquoted but otherwise unprocessed arguments to \sMTXRUN\
+     before your scripts' name (so the last entry is usually \type {--script}).}
+\mtxrunenv
+    {rawarguments}
+    {This is the whole unprocessed command||line as an array.}
+\mtxrunenv
+    {originalarguments}
+    {Like \type{rawarguments}, but with some top||level quotes removed.}
+\mtxrunenv
+    {reconstructcommandline(arg,noquote)}
+    {Tries to reconstruct a command||line from its arguments. It uses \type
+     {originalarguments} if no \type {arg} is given. Take care: due to the
+     vagaries of shell command||line processing, this may or may not work when
+     quoting is involved.}
+\stopmtxrunenvironment
+
+\type{environment} also stores various bits of information you may find useful:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {validengines}
+    {This table contains keys for \type {luatex} and \type {luajittex}. This is
+     only relevant when \sMTXRUN\ itself is called via \LUATEX's \type {luaonly}
+     option.}
+\mtxrunenv
+    {basicengines}
+    {This table maps executable names to \type{validengines} entries.}
+\mtxrunenv
+    {default_texmfcnf}
+    {This is the \type {texmfcnf} value from \type {kpathsea}, processed for use
+     with \MKIV\ in the unlikely event this is needed.}
+\mtxrunenv

+\mtxrunenv
+    {ownbin}
+    {The name of the binary used to call \sMTXRUN.}
+\mtxrunenv

+\mtxrunenv
+    {texos}
+    {Operating system root directory name.}
+\mtxrunenv
+    {texroot}
+    {\CONTEXT\ root directory path.}
+\stopmtxrunenvironment
+
+As well as some functions:
+
+\startmtxrunenvironment
+\mtxrunenv
+    {texfile(filename)}
+    {Locates a {\TEX} file.}
+\mtxrunenv
+    {luafile(filename)}
+    {Locates a \LUA\ file.}
+\mtxrunenv
+    {loadluafile(filename,version)}
+    {Locates, compiles and loads a \LUA\ file, possibly in compressed \type {.luc}

+    {Locates and compiles a \LUA\ file, returning its contents as data.}
+\mtxrunenv

+\stopsubsection
+
+\startsubsection[title=Shell return values]
+
+As explained earlier, the shell return value of \sMTXRUN\ normally indicates
+whether the script was found. If you are running a \CONTEXT\ release newer than
+September 2018 and want to modify the shell return value from within your script,
+you can use \type {os.exitcode}. Whatever value you assign to that variable will
+be the shell return value of your script.
