update-fmtlang

       related configuration files


SYNOPSIS
       update-language [options]
       update-fmtutil [options]


DESCRIPTION
       This manual page explains briefly the usage of the three TeX configura-
       tion update programs update-language and update-fmtutil.

       The  update-fontlang script should not be called directly, but only via
       the two described links.  For a more in-depth description,  please  see
       the   document   TeX  on  Debian  in  /usr/share/doc/tex-common/TeX-on-
       Debian.txt.gz (also available as HTML and PDF).

       The programs update-language and update-fmtutil create  or  update  the
       configuration  files language.dat and fmtutil.cnf, respectively.  These
       files define the hyphenation patterns to be loaded  into  LaTeX-related
       TeX  formats  (language.dat),  and  the  list  of formats to be created
       (fmtutil.cnf).

       These programs can be used either in  system-wide  mode  if  called  by
       root, or in a user-specific mode if called by a user without super-user
       privileges.

OPTIONS
       -c DIR, --conf-dir=DIR
              directory where the user-specific configuration files are looked
              for  in  user-specific  mode (default TEXMFCONFIG/language.d for
              update-language and TEXMFCONFIG/fmt.d for update-fmtutil,  where
              TEXMFCONFIG is usually $HOME/.texmf-config).

       -o FILE, --output-file=FILE
              file  to  write the output to. Per default, in system-wide mode,
              update-language writes to /var/lib/texmf/tex/generic/config/lan-
              guage.dat        and        update-fmtutil       writes       to
              /var/lib/texmf/web2c/fmtutil.cnf.

       --checks
              perform sanity checks on the generated config  file.  Don't  use
              this in maintainer scripts.

       --quiet
              don't write anything to the standard output during normal opera-
              tion

       --help print a summary of the command-line usage and exit

       --version
              output version information and exit


       tain a magic header:

       # -_- DebPkgProvidedMaps -_-

       which  local  administrators  should not remove.  From the files with a
       magic header, only those files which are also  listed  in  one  of  the
       files  in  /var/lib/tex-common/language-cnf/  for  update-language, and
       /var/lib/tex-common/fmtutil-cnf/  for  update-fmtutil,   are   actually
       included  into  the  final  output file. This way, local changes to the
       configuration can be preserved while the package is in state 'rc' (that
       is,  the  package  is  removed,  but  its configuration files are still
       present).  For details about this mechanism, package maintainers should
       consult  the Debian TeX Policy.  As a special case, the files for Jade-
       TeX and xmlTeX are only included if there is already  a  file  for  the
       LaTeX format (see TeX on Debian for details).

       The  user-specific mode provides a way for a non-admin user to override
       system-wide settings.  In this mode, update-language writes  to  TEXMF-
       VAR/tex/generic/config/language.dat, and update-fmtutil writes to TEXM-
       FVAR/web2c/fmtutil.cnf, where  TEXMFVAR  is  usually  $HOME/.texmf-var.
       Furthermore,  files  present  within  the  user-specific  configuration
       directories are included in addition to the files present in  the  sys-
       tem-wide  configuration  directories.  In case the same filename exists
       in the system-wide configuration directory and the  user-specific  con-
       figuration  directory,  the  user-specific  file is used instead of the
       system-wide one. The user-specific configuration directories are TEXMF-
       CONFIG/language.d for update-language and TEXMFCONFIG/fmt.d for update-
       fmtutil, where TEXMFCONFIG is usually $HOME/.texmf-config. The  system-
       wide  configuration directories have the same names, but are located in
       /etc/texmf/ instead of TEXMFCONFIG.

       Note that changes introduced by updates of packages are not  propagated
       to the user's configuration files. This has to be done by hand.


FILES
       /var/lib/texmf/tex/generic/config/language.dat
              This  file is generated or updated by update-language in system-
              wide mode and contains a list of the hyphenation patterns loaded
              into LaTeX-based formats by fmtutil-sys.

       /var/lib/texmf/web2c/fmtutil.cnf
              This  file  is generated or updated by update-fmtutil in system-
              wide mode and contains a list of  formats  to  be  generated  by
              fmtutil-sys.

       /etc/texmf/language.d/name.cnf
              Input files for update-language

       /etc/texmf/fmt.d/name.cnf
              Input files for update-fmtutil

       /var/lib/tex-common/language-cnf/package.list
              Lists  the  file(s)  installed  by  package  in  /etc/texmf/lan-
              to  be  found  in /usr/share/doc/tex-common/TeX-on-Debian.txt.gz
              (also available as HTML and PDF), describing in more detail  how
              to  setup  and maintain a TeX system in Debian. It also includes
              details on user-specific configuration.

       Debian TeX Policy
              to   be   found   in   /usr/share/doc/tex-common/Debian-TeX-Pol-
              icy.txt.gz  (also  available  as  HTML  and PDF), describing the
              internals and the TeX Policy established on the Debian TeX mail-
              ing-list  (debian-tex-maint@lists.debian.org). Intended audience
              is mainly developers packaging TeX-related resources for Debian.

       dh_installtex(1)
              a debhelper-like script for managing the installation  of  files
              into  the  system-wide  configuration  directories;  this script
              helps to write Debian packages containing TeX-related  resources
              that conform to the Debian TeX Policy.
