CHANGES.ENG (emTeX DISTRIBUTION) 19-Sep-1995
==============================================================================
This document describes the most important changes to the emTeX
distribution.
25-Jun-1995
===========
Directory structure
-------------------
- The directory structure has been reorganized. There are no longer
any files in directory \emtex; executable files have been moved to
\emtex\bin, other files to \emtex\data. In consequence, you have to
change your PATH. Moreover, all files of \emtex\mfinput,
\emtex\texinput, and \emtex\tfm have been moved to subdirectories of
these directories
Unfortunately, there are third-party packages which do no yet use
the new directory structure and do not support subdirectory search.
It is recommended to install those packages in their own tree for
now
- All emx stuff (with the exception of rsx) has been moved out of the
\emtex directory tree to its own directory tree rooted at \emx
(package emxrsx). In consequence, you might have to change your
PATH and LIBPATH
Packaging
---------
- Info-ZIP's UnZip is now used instead of pkunzip for unpacking ZIP
archive files
- Packages have been rearranged, split, combined, and renamed. Some of
the ZIP archive files do not fit on 360KB and 720KB diskettes
- Format files for TeX and base files for METAFONT are no longer
shipped. You have to create them yourself. The documentation
explains how to do that. The new makefmt tool will assist you in
creating TeX formats
- emremove.exe and emdelete.exe are now shipped in first.zip; these
programs were formerly called remove.exe and delete.exe
Fonts
-----
- Both the METAFONT modes and the Computer Modern font sources have
been changed, resulting in changed character shapes. You should
delete all old fonts to avoid mixing old and new shapes
- Only a collection of frequently used fonts is shipped pre-compiled.
Missing fonts will be generated on the fly as required. In
consequence, you have to install METAFONT and MFjob
- The font library files have been renamed. A base set of fonts is
shipped in a FLI file named xx_base.fli where xx depends on the
METAFONT mode. You can put extra fonts into xx_more.fli. The
dvidrv configuration files now try to load xx_base.fli and
xx_more.fli (instead of xx_0.fli through xx_5.fli)
- A METAFONT mode for the HP DeskJet has been added and pre-compiled
fonts for the HP DeskJet are now available. DeskJet users should
switch from LJ fonts to DJ fonts. Do not mix LJ and DJ fonts!
- Some METAFONT modes have been renamed. You can find the new names
in \emtex\mfinput\etc\local.mf
LaTeX
-----
- Both LaTeX2e and the obsolete LaTeX 2.09 are provided
- As the order in which subdirectories are visited for locating files
is not completely specified, you should list either
\emtex\texinput\latex2e or \emtex\texinput\latex209 in the TEXINPUT
environment variable, preceding \emtex\texinput! (the bang is part
of TEXINPUT's value and enables subdirectory search). The makefmt
tool automatically creates batch files which temporarily adjust
TEXINPUT appropriately. Therefore, you don't have to set TEXINPUT
unless you use the LaTeX format files without those batch files
New features
------------
- Most programs now support subdirectory search: On request, either
one level of subdirectories or the entire hierarchy of
subdirectories of a given directory is searched for locating files.
This feature is enabled by appending `!' or `!!', respectively, to
the directory name listed in an environment variable. One level of
subdirectories is searched for the default directories
- To specify the root of the emTeX directory tree, setting one
environment variable, EMTEXDIR, is now sufficient unless you change
the directory structure. However, there are some exceptions such as
MakeIndex. Moreover, TEXINPUT should be set to select LaTeX2e
vs. LaTeX 2.09 (unless you use the batch files created by makefmt).
The EMTEXDRV environment variable is history
- Long file names are now supported on OS/2's HPFS. If a file with a
long name cannot be found or created, its name will be truncated
according to the `5+3.3' and `8.3' rules
- 32-bit versions of TeX, METAFONT, BibTeX, and MakeIndex are now
provided
- The DVI drivers support more printers and have a lot of new
features. A screen previewer for the OS/2 Presentation Manager is
now included. dvimsp's job has been taken over by dvidot
- tex286.exe, mf286.exe, etc. have been renamed to tex186.exe,
mf186.exe, etc.
- Various limits of emTeX, METAFONT, and utilities have been raised
- emTeX optionally supports the \charsubdef primitive (MLTeX)
- Programs which use graphics mode (dviscr, mf, pkedit) support
additional graphics adapters and modes
- TeXcad is no longer Shareware
- Some documentation files are also available as OS/2 on-line manuals
for viewing with OS/2's `view' command
- Package dvidrvma is currently not available
- IMPORTANT: The command line options of emdelete.exe (formerly called
delete.exe) have changed
