-.TH CTXTOOLS "1" "January 2007" "ctxtools 1.3.3" "ConTeXt"
-
-.SH NAME
-ctxtools \- clean up temporary ConTeXt files, install latest ConTeXt
-
-.SH "SYNOPSIS"
-\fBctxtools\fP [ \fIOPTION\fP ... ]
-
-.SH DESCRIPTION
-\fBctxtools\fP is useful for dealing with ConTeXt source and generated
-files and for installing new versions of ConTeXt.
-
-.SH "OPTIONS"
-.TP
-.B --help
-Print the available options.
-.TP
-.B --purgefiles
-Get rid of many temporary files generated by ConTeXt. You can give the
-.B --all
-option to remove a larger fraction of those files,
-and the
-.B --recurse
-option to remove these files also in subdirectories.
-.TP
-.B --contextversion
-Show the date of the ConTeXt macros and the format file. Useful after
-upgrading ConTeXt (perhaps using \fB--updatecontext\fP) to check
-whether the new formats and macros are visible to the TeX path
-searches (see
-.BR kpsewhich (1).
-.TP
-.B --updatecontext
-Download the latest ConTeXt distribution and install it in the
-TEXMFLOCAL tree (see
-.BR kpsewhich (1)
-for information on
-TeX path searching). TEXMFLOCAL usually points to a system-wide
-location. If you want to install the new ConTeXt in your home
-directory (i.e. an install for one user), then set the TEXMFLOCAL
-environment variable while running
-.BR ctxtools .
-For example, using the syntax of the Bourne shell
-.BR sh (1):
-.EX
-TEXMFLOCAL=$HOME/texmf ctxtools --updatecontext
-.EE
-.TP
-.B --documentation
-Generate a \fI.ted\fP file from the source file. See also the
-\fB--module\fP option to
-.BR texexec (1).
-.TP
-\fB--patternfiles\fP [languagecode]
-Generate pattern files. You can also give the
-\fB--all\fP, \fB--xml\fP, and \fB--utf8\fP options.
-
-.SH "ENVIRONMENT"
-.TP

-.SH "NAME"
-texexec \- front end to the ConTeXt typesetting system
-
-.SH "SYNOPSIS"
-\fBtexexec\fP [ \fIOPTION\fP ... ] \fIFILE\fP [ ... ]
-
-.SH "DESCRIPTION"
-
-\fBtexexec\fP, a \fBruby\fP(1) script,
-is the command-line front end to the ConTeXt typesetting
-system, an extensive macro package
-built on the \fBtex\fP(1) family of typesetting programs.
-\fBtexexec\fP provides several facilties:
-.IP \(bu
-Process a ConTeXt source file,
-performing as many runs as
-necessary of \fBtex\fP(1), \fBtexutil\fP(1), and
-MetaPost (\fBmpost\fP(1)). Options control the output
-format, the pages to process, paper size, and so forth.
-.IP \(bu
-Create new ConTeXt formats, useful during installation.
-.IP \(bu
-Post-process existing PDF files, including merging multiple
-files, and extracting and rearranging pages within a file,
-similar to the facilities provided for PostScript files by
-\fBpsnup\fP(1) or for PDF files by \fBpdftk\fP(1).
-.IP \(bu
-Extract or strip documentation from ConTeXt source files
-using \fBtexutil\fP(1).
-.IP \(bu
-Run MetaPost (\fBmpost\fP(1)) to generate figures from MetaPost source.
-.IP \(bu
-Produce proof sheets of figures used in a ConTeXt source file.
-.IP
-.SH "OPTIONS"
-
-All switches are specified in full here but can be abbreviated to the
-shortest unique prefix. Thus, \fB--env\fP works the same as
-\fB--environment\fP. With no options, \fBtexexec\fP assumes that
-the file on the command line is a ConTeXt source file, i.e. a TeX file
-in the ConTeXt dialect, and produces a PDF file using the source file.
-
-.SS "General Options"
-
-.IP "\fB--alone\fP"
-Avoid calling other programs when possible. For
-example, \fB--alone\fP will prevent \fBtexexec\fP from
-using \fBfmtutil\fP(1) to generate formats (this prevention can
-be handy when tracing installation problems).
-.IP "\fB--environments\fP\fI=\fP\fIfile[,file[,...]]\fP"
-Specify ConTeXt environment file(s), separated by commas, to use when
-processing the source file. This option is useful when converting
-from non-ConTeXt file formats without environment or layout settings.
-.IP "\fB--help\fP"
-Produce a summary of switches
-and arguments. A more detailed help is produced by including
-\fB--all\fP.
-.IP "\fB--interface=\fP\fIlanguage\fP"
-Specify the language
-ConTeXt should use to communicate with you.
-Options are
-.IP
-.RS
-.IP "\fBen\fP"
-US English
-.IP "\fBnl\fP"
-Dutch
-.IP "\fBde\fP"
-German
-.IP "\fBuk\fP"
-British English
-.IP "\fBcz\fP"
-Czech
-.IP "\fBit\fP"
-Italian
-.RE
-.IP "\fB--keep\fP"
-Preserve a few of the temporary files generated while processing by
-appending \fI.keep\fP to their name. For example, after
-.EX
-texexec --keep document.tex
-.EE
-you will find (besides \fIdocument.pdf\fP) \fIdocument.log.keep\fP
-and \fIdocument.top.keep\fP. The \fIdocument.top\fP file is where
-\fBtexexec\fP wraps \fIdocument.tex\fP with the proper ConTeXt macro
-commands to set the output format, etc.
-.IP "\fB--once\fP"
-Process a file exactly once. (By default,
-\fBtexexec\fP processes the file as many times as
-necessary to sort out all references, typeset
-\fBMetaPost\fP code, and so forth.)
-.IP "\fB--purge\fP"
-Get rid of most temporary files generated while processing the source
-file. For example,
-.EX
-texexec --purge somefile.tex
-.EE
-will generate \fIsomefile.pdf\fP, cleaning up after itself and leaving
-only one extra file, \fIsomefile.tuo\fP. See also the \fB--purge\fP
-option of
-.BR ctxtools (1)
-.IP "\fB--purgeall\fP"
-Get rid of all temporary files generated while processing the source
-file, including the \fIfilename.tuo\fP file. See also the \fB--purge
---all\fP option combination of
-.BR ctxtools (1)
-.IP "\fB--randomseed=\fP\fINNNN\fP"
-Set the random seed.
-.IP "\fB--result=\fP\fIFILENAME\fP"
-Allows you to change the
-basename of the output file. See
-\fB--mode\fP for an example.
-.IP "\fB--runs=\fP\fINUMBER\fP"
-Specify the number of runs to
-perform on a file. Overrides
-\fBtexexec\fP's calculations.
-.IP "\fB--separation\fP"
-Perform color separations.
-.IP "\fB--silent\fP"
-Suppress a few diagnostic and progress messages.
-.IP "\fB--timeout=\fP\fINNN\fP"
-Abort the run if a subprocess waits for more than \fINNN\fP seconds;
-e.g. while waiting for user input when \fBtex\fP reports an undefined
-control sequence. Useful for automated testing scripts, to make sure
-the runs finish.
-.IP "\fB--usemodules=\fP\fImodule1[,module2,[...]]\fP
-Use the comma-separated list of modules. For example, to typeset
-\fIdocument.tex\fP using the \fIbib\fP and \fIunits\fP modules:
-.EX
-texexec --usemodules=bib,units document.tex
-.EE
-.IP "\fB--verbose\fP"
-Output extra diagnostic information.
-.IP "\fB--version\fP"
-Print the version number.
-.IP
-
-.SS "Processing ConTeXt Source Files"
-
-Including specifying paper sizes, formats, and so forth.
-
-.IP "\fB--arrange\fP"
-Perform page rearrangements, which are used to produce booklets. This
-option tells ConTeXt to the first \fIn\fP-1 runs without taking
-account of arrangements, then on the last run to pay attention to
-the arrangement commands in the source file.
-.IP "\fB--batchmode\fP"
-Process the file in batchmode, which means
-to typeset the whole document even if there are errors. More
-imformation about \f(CWbatchmode\fP can be found in Donald
-E. Knuth's \fITeXbook\fP.
-.IP "\fB--nonstopmode\fP"
-Process the file in nonstopmode, which means
-to typeset the document and report errors, but not to stop at any
-error. It is similar to batchmode but more verbose. More
-imformation about \f(CWnonstopmode\fP can be found in Donald
-E. Knuth's \fITeXbook\fP.
-.IP "\fB--bodyfont=\fP\fIfont\fP"
-The name of a font to preload for use in
-setting the body of the text (OBSOLETE).
-.IP "\fB--centerpage\fP"
-Center the document on the page.
-.IP "\fB--color\fP"
-Turn on color mode. Color mode can also be set by
-commands embedded in the document. These commands
-override the \fB--color\fP option.
-.IP "\fB--convert=\fP\fIFORMAT\fP"
-Convert the input file to
-ConTeXt format from \fIFORMAT\fP before
-processing. In most cases, this conversion will result
-in a TeX file. Currently supported input
-\fIFORMAT\fPs are \fBxml\fP and
-\fBsgml\fP.
-.IP "\fB--dvipdfmx, --dvipdfm, --dpx, --dpm\fP"
-Use the TeX engine (e.g. \fBpdftex\fP or \fBpdfetex\fP)
-to make a DVI file and \fBdvipdfmx\fP(1) to turn it
-into PDF.
-.IP "\fB--dvi, --ps, --dvips\fP"
-Use the TeX engine (e.g. \fBpdftex\fP or \fBpdfetex\fP)
-to make a DVI file and \fBdvips\fP(1) to turn it
-into PostScript. It's counterintuitive that \fB--dvi\fP produces
-a PostScript file in addition to the DVI file. But that's because
-\fB--dvi\fP is shorthand for \fB--dvips\fP; adding the \fB--nobackend\fP
-option prevents \fBtexexec\fP's running \fBdvips\fP(1). See also the
-\fB--engine\fP option.
-.IP "\fB--fast\fP"
-Typeset the document(s) as fast as possible without
-causing problems.
-.IP "\fB--final\fP"
-Perform a final run without skipping anything.
-This option is typically used with \fB--fast\fP.
-.IP "\fB--language=\fP\fILANGUAGE\fP"
-Set the language for
-hyphenation. Can be specified in your source file.
-Options are the same as those for \fB--interface\fP.
-.IP "\fB--mode=\fP\fIMODELIST\fP, \fB--modes=\fP\fIMODELIST\fP"
-Allows you to change the mode used while typesetting the
-source file. The \fIMODELIST\fP is a comma separated list of modes.
-Modes are a conditional-compilation facility
-like \f(CW#ifdef\fP in C. So one source file can be used to produce
-several typeset documents: one for A4 paper, one for
-screen display in full color, one for letter paper, etc. For
-example:
-.IP
-.EX
-\f(CWtexexec --pdf --mode=A4 --result=manual-a manual-t.tex\fP
-\f(CWtexexec --pdf --mode=letter --result=manual-l manual-t.tex\fP
-\f(CWtexexec --pdf --mode=screen --result=manual-s manual-t.tex\fP
-.EE
-.IP
-Here the \fB--mode\fP tells ConTeXt which
-mode directives to use when typesetting the source file. The
-\fB--result\fP option tells ConTeXt
-where to put the output file.
-.IP "\fB--modefile=\fP\fIfile\fP"
-Load this file before most of the usual processing; usually used for
-mode-related material.
-.IP "\fB--noarrange\fP"
-Ignore arrangement commands in the source file.
-.IP "\fB--nobackend\fP"
-Do not run the backend, e.g. \fBdvips\fP(1) or \fBdvipdfmx\fP(1). See
-the \fB--dvips\fP or \fB--dvipdfmx\fP options. Why would you give one
-of those options to choose a backend, yet tell \fBtexexec\fP not to
-run the backend? Because each backend has its own syntax for
-\f(CW\\special\fP calls. Specifying the backend allows the ConTeXt
-macros to use the correct syntax so that when you later run the
-backend to produce PostScript or PDF, the specials will be interpreted
-correctly.
-.IP "\fB--pages=\fP\fIPAGENUMBERLIST\fP"
-Specify the pages or page
-range to appear in the output file.
-\fIPAGENUMBERLIST\fP may be the keyword \fBodd\fP
-or \fBeven\fP; or one or more pages or page ranges separated by commas.
-For example,
-.EX
-\f(CWtexexec --pages=1,7,8-11,14 somefile.tex\fP
-.EE
-.IP "\fB--paperformat=\fP\fIKEY\fP"
-For typesetting multiple pages on a
-single piece of paper. \fIKEY\fP has the form \fBa4a3\fP
-(for printing A4 pages on A3 paper), \fBa5a4\fP
-(for printing A5 pages on A4 paper), or in general \fBaMaN\fP.
-The actual layout of the pages is specified with the
-\fB--printformat\fP option.
-.IP "\fB--pdf, --pdftex\fP"
-Use \fBpdftex\fP(1) to produce a pdf document (the default).
-.IP "\fB--printformat=\fP\fIKEY\fP"
-Specify the layout of the final
-output. \fIKEY\fP can be \fBup\fP, resulting in 2
-pages per sheet, double sided; or \fBdown\fP, resulting
-in 2 rotated pages per sheet, double sided. Use the
-\fB--paperformat\fP option to specify the original page
-and sheet size.
-.IP "\fB--utfbom\fP"
-Turn on UTF-8 encoding.
-.IP "\fB--xetex, --xtx\fP"
-Use \fBxetex\fP(1) to produce a pdf document.
-.IP
-
-.SS "Creating ConTeXt Format Files"
-
-.IP "\fB--make\fP"
-Generate a ConTeXt format file. For example, to make
-\fIcont-en.fmt\fP and have it placed in a default format directory:
-.EX
-texexec --make de
-.EE
-The most common invocation, which is used by scripts that install a new version
-of ConTeXt (see \fBctxtools\fP(1)), uses \fB--all\fP
-so that \fBtexexec\fP makes the usual formats:
-.EX
-texexec --make --all
-.EE
-.IP "\fB--local\fP"
-When searching for TeX or MetaPost formats, look in the current directory
-rather than in the location set by the kpse library. See
-.BR kpathsea (1)
-for more information on path searching.
-.IP "\fB--check\fP"
-Check and report information about the ConTeXt version, the
-distribution, the TeX engine, and the language interfaces/formats.
-
-.SS "Expert options"
-
-You should know what you're doing if you use these options!
-.IP "\fB--alpha"
-Use the TEXMFALPHA environment variable to find and
-run an alpha release of ConTeXt.
-.IP "\fB--beta"
-Use the TEXMFBETA environment variable to find and
-run a beta release of ConTeXt.
-.IP "\fB--distribution\fP\fI=dist\fP"
-Usually one of \fBstandard\fP, \fBweb2c\fP, or \fBmiktex\fP.
-\fBtexexec\fP should figure it out automatically, and you shouldn't
-need to use this option.
-.IP "\fB--engine\fP\fI=texengine\fP"
-Specify the program to do the hard work of typesetting. Currently
-either \fBpdftex\fP (the default), \fBxetex\fP, or \fBaleph\fP.
-The \fBluatex\fP value is experimental. The \fB--engine\fP
-option is not usually needed. Instead, let
-\fBtexexec\fP figure out the setting based on other command-line
-information. See for example the \fB--xetex\fP or \fB--pdf\fP
-switches.
-
-.SS "Postprocess PDF Files"
-
-.IP "\fB--combination=\fP\fIROWS\fP\fB*\fP\fICOLS\fP"
-Specify the number of pages to show on a single page. Use with
-\fB--pdfcombine\fP.
-.IP "\fB--pdfarrange\fP"
-For rearranging pages in PDF files.
-.EX
-\f(CWtexexec --pdfarrange --paperformat=a5a4 --printformat=up foo.pdf\fP
-.EE
-This command creates an A5 booklet from a PDF file
-\fIfoo.pdf\fP. \fB--pdfarrange\fP is used in
-conjunction with the following options.
-.IP "\fB--pdfcopy\fP"
-Copy and perhaps process pages from the pdf file.
-The resulting file is \fItexexec.pdf\fP by default, but you can change
-that using \fB--result\fP. Use the \fB--scale\fP option to magnify or
-demagnify the original pages and the \fB--pages\fP option to select
-the pages to copy. Here is an example using all these options:
-.EX
-texexec --pages=4-7 --pdfcopy --scale=750 --result=one images.pdf
-.EE
-It takes pages 4-7 from \fIimages.pdf\fP, scales them by 75%,
-and copies them to \fIone.pdf\fP.
-.IP "\fB--scale=\fP\fIinteger\fP"
-If the integer is less than 10, then it is taken as an (integer)
-magnification factor. Otherwise, it is taken as a magnification
-factor in TeX terms, i.e. with 1000 meaning full scale.
-.IP "\fB--paperoffset=\fP\fIdimen\fP"
-Specify the space between the
-edge of the pages and the beginning of the text block.
-.IP "\fB--backspace=\fP\fIdimen\fP"
-Specify the inside (gutter) margins.
-.IP "\fB--topspace=\fP\fIdimen\fP"
-Specify the top and bottom margin.
-.IP "\fB--markings\fP"
-Add crop marks.
-.IP "\fB--addempty=\fP\fIPAGES\fP"
-Add empty pages after the pages specified in \fIPAGES\fP. (Useful
-for, among other things, adding blank pages after a table of
-contents.)
-.IP "\fB--textwidth=\fP\fIWIDTH\fP"
-Set the width of
-the original text. Specifying this parameter with a
-single-sided original will allow ConTeXt to adjust
-the page layout for double-sided output, producing much
-more attractive results.
-
-With the \fB--pdfarrange\fP flag, specifying more
-than one file will result in all of the files being
-combined in the final result, allowing you to add title
-pages, decorated part separators, and so forth.
-
-You can also do more complex manipulations, such as
-adding additional text to the page by setting up a
-small file with layout definitions and a simple figure
-insertion loop.
-.IP "\fB--pdfcombine\fP"
-Combine multiple pages. Requires the \fB--combination\fP option.
-.IP "\fB--pdfselect\fP"
-Extract pages from a file. Use in combination with the
-\fB--selection\fP switch, as in
-.EX
-\f(CWtexexec --pdfselect --paperformat=S6
---selection=1,9,14 file-1\fP
-.EE
-which extracts pages 1, 9, and 14 from
-\fIfile-1.pdf\fP, and places them in
-\fItexexec.pdf\fP (the default output filename if
-an output file isn't specified).
-
-See \fB--pdfarrange\fP for other
-options.
-.IP "\fB--selection=\fP\fIPAGES\fP"
-Specify pages to be affected by
-another option. See \fB--pdfarrange\fP and
-\fB--pdfselect\fP for examples.
-
-.SS "XML handling"
-.IP "\fB--filters=\fP\fIfilter1[,filter2[,...]]\fP
-Specify XML filters to use.
-
-.SS "Extract or Strip Out Documentation"
-
-.IP "\fB--listing\fP"
-Produce a typeset version of the source code in
-\fIFILE\fP. You can specify the format of the output
-file. For example, use
-.EX
-\f(CWtexexec --ps --listing readme.now\fP
-.EE
-to produce a PostScript file called
-\fItexexec.ps\fP.
-
-See also \fB--backspace\fP, \fB--topspace\fP, and \fB--result\fP.
-.IP "\fB--module\fP"
-Create documentation for ConTeXt,
-MetaPost (see \fBmpost\fP(1)),
-.BR perl (1),
-and
-.BR ruby (1)
-modules.
-Converts the documentation to ConTeXt format and
-then typesets a documentated version of the source file.
-
-Documentation lines in ConTeXt source files are
-specified by beginning lines with these strings:
-
-\f(CW%C\fP : Copyright information
-
-\f(CW%D\fP : Documentation lines
-
-\f(CW%I\fP : TeXEdit information lines (mostly in Dutch)
-
-\f(CW%M\fP : Macro code needed to processs the documentation
-
-\f(CW%S\fP : Suppressed lines
-
-The same forms can be used for Perl or ruby scripts, except that the \f(CW%\fP
-character (the TeX comment character) is replaced by \f(CW#\fP (the
-Perl comment character).
-
-See also the \fB--documentation\fP option to
-.BR ctxtools (1).
-
-.SS "Process MetaPost Figures"
-
-.IP "\fB--mpsformats=\fP\fIname\fP"
-The name of a MetaPost format file, e.g. \fBmetafun\fP (the default).
-.IP "\fB--mptex\fP"
-Strips out and typesets TeX code embedded in a
-MetaPost file.
-.IP "\fB--nomp\fP"
-Do not run \fBmpost\fP(1), even if needed.
-.IP "\fB--nomprun\fP"
-Do not run \fBmpost\fP(1) on embedded
-MetaPost code.
-
-.SS "Producing Proof Sheets of Figures"
-
-Generate information and proof sheets of one or more (non-EPS)
-graphics files. For example,
-.EX
-texexec --figures *.png *.jpg
-.EE
-scans the current directory for PNG and JPG files
-and extracts useful information about their sizes and types. By
-default, this information is stored in
-.IR rlxtools.rli .
-Then the given figures are made into a proof sheet (by default
-\fItexexec.pdf\fP) according to the method specified by the
-\fB--method\fP option. Note that newer versions of
-.BR pdftex (1)
-do not support TIFF inclusion.
-.IP "\fB--method=\fP\fIALTERNATIVE\fP"
-Specify one of three options to produce the document containing the images
-used in the source file:
-
-\fBa\fP : A proof sheet with additional
-information provided for each figure (the default)
-
-\fBb\fP : A proof sheet with the graphics only
-
-\fBc\fP : One figure per page, with the page
-clipped to the bounding box of the
-figure
-
-See also \fB--paperoffset\fP,
-which allows you to specify an offset to be added to
-the page, as in
-.EX
-texexec --figures --method=c --paperoffset=.5cm *.pdf *.png *.jpg
-.EE
-
-.SH "USAGE"
-
-Each ConTeXt user interface (language) has its own format. The
-following command generates two formats, one using the English
-interface for typesetting in English, and one for Dutch:
-.EX
-\f(CWtexexec --make en nl\fP
-.EE
-
-By default, the language used for typesetting matches the
-user-interface language (set with
-\fB--interface\fP. It is possible to use one
-language for typesetting and another for messages by changing the
-relevant settings in \fIcont-usr.tex\fP. These languages can
-also be changed on the command line with a command such as
-.IP
-.RS
-\f(CWtexexec --make --language=pl,cz,sk en\fP
-.RE
-.IP
-That command generates a ConTeXt format file with an English user
-interface, and the main language set to Polish (\fBpl\fP). Czech
-and Slovak hyphenation patterns are also loaded
-so that Czech and Slovak text included in a source file will be
-typeset properly (\fBcz\fP and \fBsk\fP).
-.IP o
-When the appropriate formats are present, a file can be typeset
-by typing
-.EX
-\f(CWtexexec test\fP
-.EE
-.IP
-\fBtexexec\fP tries to determine what interface it should use to
-typeset \fItest.tex\fP by looking for a line such as
-.IP
-.EX
-\f(CW% interface=en tex=pdftex output=pdftex\fP
-.EE
-.IP
-at the top of the file (i.e., on the very first line). This line is
-equivalent to \fBTeX\fP's format line, ``&\fIFORMAT\fP'').
-.IP
-By default, \fBtexexec\fP will produce a PDF file using \fBpdftex\fP(1). The
-\fB--dvips\fP flag tells \fBtexexec\fP to produce a PostScript
-file instead.
-.IP
-After an error-free run, \fBtexexec\fP will run \fBtexutil\fP(1) to
-determine whether additional runs of \fBtex\fP(1) (or
-\fBpdftex\fP(1)) or any utility programs (e.g., \fBbibtex\fP(1),
-\fBmakeindex\fP(1)) are necessary. You can suppress these
-additional runs by specifying the \fB--once\fP or
-\fB--runs\fP flags:
-.IP
-.EX
-\f(CWtexexec --once test\fP
-\f(CWtexexec --runs=2 test\fP
-.EE
-.IP
-
-.SH EXAMPLES
-.TP
-Produce PDF from ConTeXt source (the .tex extension is optional):
-\f(CWtexexec file.tex\fP
-.TP
-Same as the above but without rerunning for crossreferences, etc.:
-\f(CWtexexec --once file.tex\fP
-.TP
-Produce PostScript from ConTeXt source:
-\f(CWtexexec --ps file.tex\fP
-.TP
-Produce file-a4.pdf using conditional compilation (modes):
-\f(CWtexexec --mode=a4 --result=file-a4 file.tex\fP
-.TP
-Generate format (.fmt) files used by ConTeXt (used during installation):
-\f(CWtexexec --make --all\fP
-
-
-.SH "INITIALIZATION"
-.IP
-\fBtexexec\fP requires ruby. On Unix and Unix-like systems, no special
-steps have to be taken to get \fBtexexec\fP to work beyond installing
-ruby and having the \fBruby\fP(1) binary in your path.

-.SH "NAME"
-texmfstart \- run ConTeXt scripts, make ConTeXt wrapper scripts, view documents
-
-.SH "SYNOPSIS"
-\fB texmfstart\fP [ \fIoptions ...\fP ] [ \fIfilename\fP ] [ \fIarguments ...\fP ]
-
-.SH "DESCRIPTION"
-ConTeXt is a typesetting system based on the
-.BR tex (1)
-family of programs.
-.B texmfstart
-is a ConTeXt meta-script that can run subordinate
-scripts (subscripts?) such as
-.BR texexec (1),
-.BR ctxtools (1),
-or
-.BR pdftools (1).
-It can also generate short wrapper scripts to simplify common uses.
-These scripts are often called
-.I stubs
-in the ConTeXt documentation. The options control
-.BR texmfstart 's
-behaviour, and the arguments are passed
-to the program identified by
-.IR filename .
-
-If the filename is a document, then
-.B texmfstart
-will start a viewer for that document. For example:
-.EX
-texmfstart showcase.pdf
-.EE
-will start an appropriate viewer for
-.IR showcase.pdf .
-See the
-.B EXAMPLES
-section.
-
-.SH OPTIONS
-
-.SS General:
-.TP
-.B --help, --version
-print version information, usage, and examples.
-.TP
-.B --verbose
-print status and progress information, for example what commands are
-being executed.
-.TP
-.B --clear
-don't pass info about locations to child processes.
-
-.SS Running a program:
-.TP
-.B --arguments=\fIstr\fP
-an alternative for providing the arguments to be passed. For example,
-.EX
-texmfstart --arguments=b.tex texexec
-.EE
-will pass
-.I b.tex
-as the argument to
-.BR texexec .
-.TP
-.B --report
-dry run: report what command would be run, but do not run it
-.TP
-.B --locate
-dry run: like \f(CW--report\fP but doesn't print the trailing newline.
-.TP
-.B --browser
-view the document in a web browser (for Windows).
-.TP
-.B --file=\fIfilename\fP
-an alternative way to specify the file (the program to run or document
-to open).
-.TP
-.B --direct
-run a program without searching for its location (assumes that the
-program is on the PATH).
-.TP
-.B --execute
-use the
-.BR ruby (1)
-.I exec
-function instead of its
-.I system
-function.
-.TP
-.B --program=\fIstr\fP
-the program space where
-.BR kpsewhich (1)
-will search (default: context). This information is given to
-.B kpsewhich
-as its \f(CW-progname\fP option. Usually you don't need this option.
-
-.SS Creating startup scripts:
-.TP
-.B --make
-create a wrapper script or batch file to run the given file.
-The wrapper scripts are put in the current path, which usually means
-the current directory. If
-\fIall\fP is given as the file, e.g.
-.EX
-texmfstart --make all
-.EE
-then make all the ConTeXt wrapper scripts (the stubs).
-.TP
-.B --windows
-when making a wrapper script (stub), create a Windows batch (.bat) file.
-Usually you
-do not need to specify this option, as
-.B texmfstart
-will figure out what operating system you are using.
-.TP
-.B --linux
-when making a wrapper script, create a Unix shell script. Usually you
-do not need to specify this option, as
-.B texmfstart
-will figure out what operating system you are using.
-.TP
-.B --stubpath=\fIpath\fP
-specify where to put the wrapper scripts (stubs).
-.TP
-.B --indirect
-always use
-.I texmfstart
-in the wrapper script (stub).
-
-.SS Document viewing:
-.TP
-.B --page=\fInumber\fP
-open the document at this page.
-
-.SS Environments and paths:
-.TP
-.B --path=\fIstr\fP
-change to the specified path.
-.TP
-.B --tree=\fIstr\fP
-use the given TEXMF tree.
-.TP
-.B --autotree
-automatically determine the TEXMF tree to use (the default).
-.TP
-.B --environment=\fIstr\fP
-use the given environment file. Its syntax is given in the
-.I mtexmfstart.pdf
-manual.
-.TP
-.B --showenv
-print the environment variables known at runtime
-
-.SS Conditional execution:
-.TP
-.B --iftouched=\fIfile1,file2\fP
-run only when the given files have different timestamps.
-.TP
-.B --ifchanged=\fIstr\fP
-run only when the given file has changed (based on its last-computed MD5
-checksum).
-
-.SS Special features:
-.TP
-.B --edit
-open the given file in an editor.
-
-.SH "FILENAME PREFIXES"
-.SS
-Optional prefixes determine the method used to search for the specified file:
-.TP
-.I bin:filename
-expanded name based on the PATH environment variable
-.TP
-.I kpse:filename
-expanded name based on
-.BR kpsewhich (1)
-result
-.TP
-.I rel:filename
-expanded name relative to the current directory
-.TP
-.I env:name
-expanded pathname based on environment variable
-.I name
-.TP
-.I path:filename
-path part of filename as located by
-.BR kpsewhich (1)
-
-.SH EXAMPLES
-.TP
-\f(CWtexmfstart texexec.rb file.tex\fP
-Locate the
-.I texexec.rb
-script and run it with
-.I file.tex
-as its argument. In other words, make
-.I file.pdf
-from
-.IR file.tex .
-If
-.BR texexec (1)
-is properly installed on your system,
-this common invocation can be shortened to
-.EX
-\f(CWtexexec file.tex\fP
-.EE
-.TP
-\f(CWtexmfstart texexec file.tex\fP
-Locate the
-.BR texexec (1)
-program (currently a
-.BR ruby (1)
-script,
-.IR texexec.rb )
-and run it with
-.I file.tex
-as its argument, producing
-.I file.pdf.
-This invocation can be shortened to
-.EX
-texexec file.tex
-.EE
-.TP
-\f(CWtexmfstart ctxtools --updatecontext\fP
-Run the
-.BR ctxtools (1)
-script, updating the ConTeXt installation. This
-invocation is equivalent to
-.EX
-ctxtools --updatecontext
-.EE
-.TP
-\f(CWtexmfstart pstopdf --method=3 cow.eps\fP
-Convert
-.I cow.eps
-to PDF using method 3 of
-.BR pstopdf (1).
-This invocation is equivalent to
-.EX
-pstopdf --method=3 cow.eps
-.EE
-.TP
-\f(CWtexmfstart --make --stubpath=/usr/local/bin texexec\fP
-Make a wrapper script (stub), either a shell script
-.I /usr/local/bin/texexec
-on Unix, or a batch file \fI\\usr\\local\\bin\\texexec.bat\fP
-on Windows. On Unix (and maybe on Windows?), you need to make
-the script executable; see
-.BR chmod (1).
-.TP
-\f(CWtexmfstart --edit kpse:cont-sys.tex\fP
-Locate and edit the \fIcont-sys.tex\fP configuration file.
-.TP
-\f(CWtexmfstart --ifchanged=whatever.mp texexec --mpgraphic whatever.mp\fP
-Rerun
-.B texexec
-if
-.I whatever.mp
-has changed since the last use of
-.IR --ifchanged .
-.TP
-\f(CWtexmfstart --ifchanged=whatever.mp bin:echo rerun MetaPost\fP
-If the
-.I whatever.mp
-source file has changed since the last use of
-.IR --ifchanged ,
-then use the
-.BR echo (1)
-command to tell the user to rerun MetaPost
-.RB "(see " mpost (1)).
-This example shows that
-.B texmfstart
-can be used to run any script, not just ConTeXt scripts. The
-\f(CWbin:\fP prefix tells
-.B texmfstart
-not to search for
-.I echo
-in the TEXMF tree(s), but to assume that it's an executable somewhere
-on the PATH.
-.TP
-\f(CWtexmfstart --ifchanged=whatever.mp --direct echo rerun MetaPost\fP
-This invocation has the same effect as the preceding example, but
-using \f(CW--direct\fP instead of the \f(CWbin:\fP prefix, again to tell
-.B texmfstart
-not to search for the
-.I echo
-command.
-
-.SH FILES
-.TP
-.I file.md5
-MD5 checksum file used for the \f(CW--ifchanged\fP option.
-
-.SH ENVIRONMENT
-.TP
-PATH
-For expanding filenames given with a
-.I bin
-prefix.
-.TP
-TEXMFSTART_EDITOR, EDITOR, editor
-Editor to use with
-.IR --edit .
-The environment variables are looked up in that order, with the first
-setting found taking priority.

--- This script is based on texmfstart.rb but does not use kpsewhich to
--- locate files. Although kpse is a library it never came to opening up
--- its interface to other programs (esp scripting languages) and so we
--- do it ourselves. The lua variant evolved out of an experimental ruby
--- one. Interesting is that using a scripting language instead of c does
--- not have a speed penalty. Actually the lua variant is more efficient,
--- especially when multiple calls to kpsewhich are involved. The lua
--- library also gives way more control.

-<p>This version uses <l n='lpeg'/>. We follow the same approach as before, stack and top and
-such. This version is about twice as fast which is mostly due to the fact that
-we don't have to prepare the stream for cdata, doctype etc etc. This variant is
-is dedicated to Luigi Scarso, who challenged me with 40 megabyte <l n='xml'/> files that
-took 12.5 seconds to load (1.5 for file io and the rest for tree building). With
-the <l n='lpeg'/> implementation we got that down to less 7.3 seconds. Loading the 14
-<l n='context'/> interface definition files (2.6 meg) went down from 1.05 seconds to 0.55.</p>
-
-<p>Next comes the parser. The rather messy doctype definition comes in many
-disguises so it is no surprice that later on have to dedicate quite some
-<l n='lpeg'/> code to it.</p>

-<!DOCTYPE Something PUBLIC "... ..." "..." [ ... ] >
-<!DOCTYPE Something PUBLIC "... ..." "..." >
-<!DOCTYPE Something SYSTEM "... ..." [ ... ] >
-<!DOCTYPE Something SYSTEM "... ..." >
-<!DOCTYPE Something [ ... ] >
-<!DOCTYPE Something >

-
-<p>The code may look a bit complex but this is mostly due to the fact that we
-resolve namespaces and attach metatables. There is only one public function:</p>
-
-<typing>
-local x = xml.convert(somestring)
-</typing>
-
-<p>An optional second boolean argument tells this function not to create a root

-to collect tables in memory and reuse them when possible based

-stored in the saved table which makes it possible to change the
-table structures without bothering about the disk cache.</p>
