This is the installation program of the TeX Live distribution.

The installation procedure is simple: just go through the
menus until you are happy with the way all options are set up,
and then do <I> (start installation).

To select a menu item (a letter or a number marked with brackets)
just enter the corresponding letter or number and press return
(the letters are case insensitive except when collections
are being selected). Do not enter the 
angle brackets <> themselves.

We will now consider each menu item in more detail:

======================================================================
  The collections menu (<C>)
======================================================================

The collections menu allows you to select and deselect standard
collections. Each collection --- TeX macro files, Metafont font
families, and so on --- consists of several packages.

======================================================================
  The language collections menu (<L>)
======================================================================

The language collections menu allows you to select and deselect
language support collections. Each collection consists of several
packages, which provide features like hyphenation files and fonts.

======================================================================
  The binary systems menu (<B>)
======================================================================

The systems menu allows you to select and deselect 
the binary packages for various different platforms.

======================================================================
  The directories menu (<D>)
======================================================================

The TeX Live distribution will be installed in a single directory tree
(TEXDIR). You may choose any directory you like
since there are no absolute paths compiled into the binaries. Instead,
the Kpathsea library selfdir feature ensures that all
paths are relative to the location of the binaries.

The platform independent files are stored in a directory tree in
TEXDIR/texmf. There is also an extra directory for performing
administrative tasks like change of configuration and languages. This
is where all format files are stored. It defaults to TEXDIR/texmf-var.

This system allows you to mount your
TEXDIR/texmf tree read-only.

======================================================================
  The options menu (<O>)
======================================================================

The options are not applicable to all installations.  Set them as
appropriate for yours.

======================================================================
  The schemes menu (<S>)
======================================================================

You can choose from a number of different installation
schemes for TeX Live. Selecting one of these selects
some collections in the Collections and Languages lists.
which you can subsequently modify.

"alternate fonts directory":
============================

You can choose an alternate directory for automatically generated fonts;
the default is TEXMFSYSVAR/fonts

One disadvantage may be that new fonts are not shared.  I.e., if you
set this to /tmp, and users on two different machines need the same
font, it will be built twice, once on each machine.

"symlinks in standard directories"
==================================

You can make the binaries, man pages, and info files available on your
system in either (or both) of two ways:
  1) install them in "standard places" that are searched for these files
  2) change your search paths to include the new directories

If you select the "symlinks" option, symbolic links will be installed in
the directories you choose. Note that if you share the TeX Live installation
accross several machines across NFS and if the chosen "standard places" are
not shared, you need to create the symbolic links on each client, too
(or use method 2 on your clients).

If you do not use the "symlinks" option, you probably need to set up
your search paths (PATH, MANPATH, INFOPATH).

"do not install doc or source trees"
====================================
These options are not recommended, but you can use them to save space. 
Normally all packages are installed with the source and/or documentation,
but these are not needed to actually run the software. If you
are installing a system for other people, it would be unfriendly to
select these options; if you know what you are doing and need a
minimal disk footprint, go ahead


======================================================================
  Other commands (<I>, <H>, <R> and <Q>
======================================================================

Well, this is easy to explain:
  <R> does not install the system, but sets you to run off the CD
  <I> starts the installation after you are happy with the setup
  <H> displays this help
  <Q> quits the installation program

# dvipsPreferOutline
#
# Should dvips (by default) prefer bitmap fonts or outline fonts
# if both are available? Independent of this setting, outlines
# can be forced by putting "p psfonts_t1.map" into a config file
# that dvips reads. Bitmaps (for the fonts in question) can
# be forced by putting "p psfonts_pk.map" into a config file.
# We provide such config files which can be enabled via
# dvips -Poutline ... resp. dvips -Ppk ...
#
# Valid settings for dvipsPreferOutline are true / false:
dvipsPreferOutline true

#
# LW35
#
# Which fonts for the "Basic 35 Laserwriter Fonts" do you want to use and
# how are the filenames chosen? Valid settings:
#   URW:     URW fonts with "vendor" filenames (e.g. n019064l.pfb)
#   URWkb:   URW fonts with "berry" filenames (e.g. uhvbo8ac.pfb)

#   ADOBEkb: Adobe fonts with  "berry" filenames (e.g. phvbo8an.pfb)
LW35 URWkb

#
# dvipsDownloadBase35
# 
# Should dvips (by default) download the standard 35 LaserWriter fonts
# with the document (then set dvipsDownloadBase35 true) or should these
# fonts be used from the ps interpreter / printer?
# Whatever the default is, the user can override it by specifying
# dvips -Pdownload35 ... resp. dvips -Pbuiltin35 ... to either download
# the LW35 fonts resp. use the built-in fonts.
#
# Valid settings are true / false:
dvipsDownloadBase35 false

#
# pdftexDownloadBase14
#
# Should pdftex download the base 14 pdf fonts? Since some configurations
# (ps / pdf tools / printers) use bad default fonts, it is safer to download
# the fonts. The pdf files will get bigger, though.
# Valid settings are true (download the fonts) or false (don't download
# the fonts). Adobe recomments to embed all fonts.

#
# dvipdfmDownloadBase14
#
# Should dvipdfm download the base 14 pdf fonts? Since some configurations
