%  Part 1: Search paths and directories.

% This is the parent directory of our several trees, i.e.,
% /usr/local/texlive/YYYY in the original TeX Live distribution.
%
% All trees must be organized according to the TeX Directory Structure
% (http://tug.org/tds), or files may not be found.
%
% Redistributors will probably want $SELFAUTODIR/share, i.e., /usr/share.
% Kpathsea sets SELFAUTOLOC (the directory with the binary),
% SELFAUTODIR (its parent), and SELFAUTOPARENT (its grandparent).
TEXMFROOT = $SELFAUTODIR/share

% The main tree of distributed packages and programs:
TEXMFDIST = $TEXMFROOT/texmf-dist

% We used to have a separate /texmf tree with some core programs and files.
% Keep the variable name.
TEXMFMAIN = $TEXMFDIST

% The Gentoo site tree
TEXMFSITE = $TEXMFROOT/texmf-site

% Local additions to the distribution trees.
TEXMFLOCAL = $TEXMFROOT/../local/share/texmf

% TEXMFSYSVAR, where *-sys store cached runtime data.
TEXMFSYSVAR = $SELFAUTOPARENT/var/lib/texmf

% TEXMFSYSCONFIG, where *-sys store configuration data.
TEXMFSYSCONFIG = $SELFAUTOPARENT/etc/texmf

% Per-user texmf tree(s) -- organized per the TDS, as usual.  To define
% more than one per-user tree, set this to a list of directories in
% braces, as described above.  (This used to be HOMETEXMF.)  ~ expands
% to %USERPROFILE% on Windows, $HOME otherwise.
TEXMFHOME = ~/texmf

% TEXMFVAR, where texconfig/updmap/fmtutil store cached runtime data.
TEXMFVAR = ~/.texlive/texmf-var

% TEXMFCONFIG, where texconfig/updmap/fmtutil store configuration data.
TEXMFCONFIG = ~/.texlive/texmf-config

% List all the texmf trees. For an explanation of what they are, see the
% TeX Live manual.
%
% For texconfig to work properly, TEXMFCONFIG and TEXMFVAR should be named
% explicitly and before all other trees.
% 
% TEXMFLOCAL precedes TEXMFDIST because locally-installed versions
% should take precedence over distribution files -- although it is
% generally a source of confusion to have different versions of a
% package installed, whatever the trees, so try to avoid it.
TEXMF = {$TEXMFCONFIG,$TEXMFVAR,$TEXMFHOME,!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFLOCAL,!!$TEXMFSITE,!!$TEXMFDIST}

% 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 = {!!$TEXMFSYSCONFIG,!!$TEXMFSYSVAR,!!$TEXMFLOCAL,!!$TEXMFSITE,!!$TEXMFDIST}

% The system trees.  These are the trees that are shared by all users.
% If a tree appears in this list, the mktex* scripts will use
% VARTEXFONTS for generated files, if the original tree isn't writable;
% otherwise the current working directory is used.
SYSTEXMF = $TEXMFSYSVAR;$TEXMFLOCAL;$TEXMFSITE;$TEXMFDIST

% First writable tree here is used by Lua(La)TeX for the font cache.
% LuaLaTeX uses the value here, while ConTeXt uses the same variable but
% from texmfcnf.lua; therefore the two values should be kept in sync.
% (As should everything else in texmf.cnf <-> texmfcnf.lua.)
TEXMFCACHE = $TEXMFSYSVAR;$TEXMFVAR

% We use GLOBALVARTEXFONTS in order to always be able to search in the global
% font cache even if VARTEXFONTS is overridden.
GLOBALVARTEXFONTS = $SELFAUTOPARENT/var/cache/fonts

% 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 = $GLOBALVARTEXFONTS

% 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
%   TEXMFVAR = /var/lib/texmf
% is used in many distros.  In this case, set VARTEXFONTS like this
%VARTEXFONTS = $TEXMFVAR/fonts
% and do not mention it in TEXMFDBS (but _do_ mention TEXMFVAR).
%
% Remove $VARTEXFONTS from TEXMFDBS if the VARTEXFONTS directory is below
% one of the TEXMF directories (avoids overlapping ls-R files).
