TEXMFツリー

texのスタイルとかをインストーリするファイルシステムツリーをTEXMFツリーと呼ぶらしい。

$TEXMF (= {$TEXMFLOCAL,$TEXMFMAIN,$TEXMFDIST}) は，/usr/local/teTeX/share/{texmf-dist,texmf-local,texmf} (ptetex3) だったり /usr/share/{texmf-dist,texmf-local,texmf} (ptetex3 in Vine Linux) だったり /usr/local/share/{texmf-local,texmf} (W32TeX) だったり。

TEXMFツリー（の集まり）がどう構成されるかは、c:/Installed/tex/share/texmf/web2c/texmf.cnf に書いてあった。

%  Part 1: Search paths and directories.
% You can set an environment variable to override TEXMF if you're testing

% a new TeX tree, without changing anything else.

% 

% You may wish to use one of the $SELFAUTO... variables here so TeX will

% find where to look dynamically.  See the manual and the definition

% below of TEXMFCNF.
% The main tree, which must be mentioned in $TEXMF, below:

TEXMFMAIN = $SELFAUTODIR/share/texmf
% A place for local additions to a "standard" texmf tree.  For example:

TEXMFLOCAL = $SELFAUTODIR/share/texmf-local
% The main distribution tree:

TEXMFDIST = $SELFAUTODIR/share/texmf-dist
% Var tree:

% TEXMFVAR = $SELFAUTODIR/share/texmf-var
% User texmf trees can be catered for like this...

TEXMFHOME = ~/texmf
% Now, list all the texmf trees. If you have multiple trees you can

% use shell brace notation, like this:

% TEXMF = {$TEXMFLOCAL,$TEXMFMAIN,$TEXMFDIST}

% The braces are necessary.  If you set TEXFMVAR and/or TEXMFHOME, you can also

% list $TEXFMVAR and/or $TEXMFHOME in the TEXMF definition.

%
%

% If we use TEXMFVAR

%

% TEXMF = {$TEXMFVAR,$TEXMFLOCAL,$TEXMFMAIN}

%

TEXMF = {$TEXMFHOME,$TEXMFLOCAL,$TEXMFMAIN}
% Where to look for ls-R files.  There need not be an ls-R in the

% directories in this path, but if there is one, Kpathsea will use it.

% By default, this is only the !! elements of TEXMF, so that mktexlsr

% does not create ls-R files in the non-!! elements -- because if an

% ls-R is present, it will be used, and the disk will not be searched.

% This is arguably a bug in kpathsea.

TEXMFDBS = {$TEXMFLOCAL,$TEXMFMAIN};$MAKETEXPK_TOP_DIR
% The system trees.  These are the trees that are shared by all the users.

SYSTEXMF = $TEXMF
% Where generated fonts may be written.  This tree is used when the sources

% were found in a system tree and either that tree wasn't writable, or the

% varfonts feature was enabled in MT_FEATURES in mktex.cnf.

VARTEXFONTS = c:/var/tex/fonts
% It may be convenient to define TEXMF like this:

%   TEXMF = {$TEXMFHOME,!!$TEXMFLOCAL,!!$TEXMFMAIN,$HOME}

% which allows users to set up entire texmf trees, and tells TeX to

% look in places like ~/tex and ~/bibtex.  If you do this, define TEXMFDBS

% like this:

%   TEXMFDBS = $TEXMFHOME;$TEXMFLOCAL;$TEXMFMAIN;$VARTEXFONTS

% or mktexlsr will generate an ls-R file for $HOME when called, which is

% rarely desirable.  If you do this you'll want to define SYSTEXMF like

% this:

%   SYSTEXMF = $TEXMFLOCAL;$TEXMFMAIN

% so that fonts from a user's tree won't escape into the global trees.

%

% On some systems, there will be a system tree which contains all the font

% files that may be created as well as the formats.  For example

%   TEXFMVAR = /var/lib/texmf

% is used on many Linux systems.  In this case, set VARTEXFONTS like this

%   VARTEXFONTS = $TEXFMVAR/fonts

% and do not mention it in TEXMFDBS (but _do_ mention TEXFMVAR).
%

% ConTeXt

%

TEXMFCACHE = $SELFAUTODIR/share/ctxdir
