This is the file TDS.doc of the CJK macro package ver. 4.2.0 (13-Dec-1998).

The TeX Directory Structure (TDS)
---------------------------------

A working group of the American TeX Users Group (TUG) has developed the TDS
standard (available from the CTAN hosts in tex-archive/tds). That document
describes a default directory structure where and how to store the many
different files needed for a complete TeX system.

The following describes the recommended default directories used in the CJK
package for its files; $TEXMF stands for the place where the texmf directory
resides (a possibly better place for distributions based on web2c is
$TEXMFLOCAL; see texmf.cnf of your TeX package for details):

CJK TeX files (you should move the whole `texinput' tree of the CJK package
               to this place):
    $TEXMF/tex/latex/CJK/<CJK subdirs>/<CJK TeX files>
  example:
    /usr/local/web2c-7.0/texmf/tex/latex/CJK/Bg5/Bg5.cap

TrueType fonts:
    $TEXMF/fonts/truetype/<supplier>/<truetype font>
  example:
    /usr/local/teTeX/texmf/fonts/truetype/ntu/ntukai.ttf

HBF fonts:
    $TEXMF/fonts/hbf/<character set>/<hbf name stem>/<hbf files>
  example:
    /usr/local/share/texmf/fonts/hbf/jisx0208/kanji48/kanji48.{bin,hbf}

[Ideally, instead of <character set>, <supplier> should be used for HBF fonts
also, but it is often difficult to find out this information.]

ttf2pk configuration, encoding, replacement, and subfont definition files
       (*.enc, *.rpl, *.sfd):
    $TEXMF/ttf2pk
  example:
    /usr/local/texmf/ttf2pk/ttfonts.map

[ttf2tfm uses the same data, thus you should either create a directory link
pointing to $TEXMF/ttf2tfm or set the appropriate configuration variables to
this directory; for newer web2c based distributions this is $TTF2TFMINPUTS.]

hbf2gf configuration files:
    $TEXMF/hbf2gf/<config files>
  example:
    /dos/texmf/hbf2gf/gsfs14.cfg

TFM files (<supplier> for TTF resp. <character set> for HBF fonts and
           <name stem> as specified in special.map):
    $TEXMF/fonts/tfm/<character set>/<name stem>/<tfm file>
    $TEXMF/fonts/tfm/<supplier>/<name stem>/<tfm file>
  examples:
    /usr/local/teTeX/texmf/fonts/tfm/ntu/ntukai/ntukai23.tfm
    /usr/local/teTeX/texmf/fonts/tfm/big5/b5ka12/b5ka1201.tfm

PK files (<supplier> for TTF resp. <character set> for HBF files and
          <name stem> as specified in special.map)
    $TEXMF/fonts/pk/modeless/<character set>/<name stem>/<pk file>
    $TEXMF/fonts/pk/modeless/<supplier>/<name stem>/<pk file>
  example:
    /usr/local/share/texmf/fonts/pk/modeless/big5/b5ka12/b5ka1217.600pk
    /usr/local/share/texmf/fonts/pk/modeless/uw/uwcxmf/uwcxmf23.3252pk

There are further possibilities how to store PK files:

1. instead of <name>.<dpi>pk you can use dpi<dpi>/<name>.pk; example:
     /texmf/fonts/pk/modeless/big5/b5ka12/dpi600/b5ka1217.pk

2. teTeX additionally allows you to omit either <character set> resp.
   <supplier> or <name stem> or both (for PK, TFM, and MF files); example:
     /texmf/fonts/pk/modeless/b5ka12/dpi600/b5ka1217.pk


The first option is necessary on operating systems like DOS which only allow
8.3 filenames. The second option enables you to use the `!' feature of the
emTeX subdirectory searching algorithm (only one level) instead of `!!'
(search all subdirectory levels) together with its template mechanism to
make emTeX much faster in finding PK files. Now teTeX and emTeX could share
one common texmf tree.
