# $Id: latex2html.config,v 1.21 1997/07/07 00:38:57 JCL Exp $

# ################# YOU **MUST** CHECK THESE VARIABLES ####################

# Give the path to the DIRECTORY in which the latex2html files can be found.
# You can leave this alone if you run install-test.
# 
$LATEX2HTMLDIR = "/home/payne/programs/latex2html";


#  Give the paths to latex and dvips on your system:
#
$LATEX = "/usr/local/bin/latex";		# LaTeX
$DVIPS = "/usr/local/bin/dvips";		# dvips


# This specifies the type of images produced by latex2html when processing
# unknown environments and/or e.g. math formulae.
# Don't care. It will be updated by configure-pstoimg.
#
$IMAGE_TYPE='gif';# Inserted by installation script


##########  ICONSERVER  --- !! IMPORTANT !! ############################
#
# LaTeX2HTML uses many small graphics as icons within the navigation
# panels, and for other purposes.
# You *must* specify where these graphics are to be found, for use within
# your documents.
#
# IMPORTANT: This location must not only be accessible to you, but also
#            to the people who are to read your HTML documents.
#
# One option is to always use the  -local_icons switch (see below)
# to have a copy of the icons together with your HTML document.
# (This is safe, but wasteful if you have a large number of documents.)
#
# A better option is to set  $ICONSERVER  to point to a location that
# is known to always (at least in principle) be available publicly.
#
# The default value for  $ICONSERVER  given below is within the local 
# $LATEX2HTMLDIR. If this is *not* to be publicly available then you 
#  **should change the value of $ICONSERVER to a site that is**.
#
# You probably have to talk to your Webmaster to provide access to the
# icon directory. Some hints:
# a) It's ok to set $ICONSERVER just to "/path/to/icons.$IMAGE_TYPE" (without
#    the internet address) if /path/to is valid for your file system, *and*
#    if www_root/path/to points to the same directory. Normally the www area
#    is located in some subsidary directory, which is pointed to by www_root
#    (the entry 'Document Root' of the http daemon's srm.conf file).
#    Make the Webmaster add appropriate links in that directory that help
#    locate the icon directory, or set up an Alias in srm.conf.
# b) To check if the icons can be displayed properly, invoke the browser
#    with the *http URL to your site*, and click down to your document.
# c) If you have $LOCAL_ICONS set, your document will accumulate a pretty
#    amount of redundant icons if you make use of segmentation.
#    In this case, customize &img_tag to use a central directory, say,
#    "../icons".
#
$ICONSERVER = "http://www.stsci.edu/icons/";


# ####### YOU *MAY* WANT/NEED TO CHANGE SOME OF THESE VARIABLES  ##############

# If you have dvips 5.62 or higher, you can turn on generation of EPS files
# by uncommenting the following line. Warning: dvips does not support
# included EPS figures very well. However if you don't make use of
# complicated image include commands like \includegraphics, this option
# will speed up image generation a *lot*.
#
#$DVIPS = "dvips -E";
$DVIPS = "dvips";


# (Note: this here is old, don't worry unless you really run into trouble.)
#
# Some dvips programs generate postscript images in the reverse order by
# default. If your inlined images are all screwed up try uncommenting
# the following line:
#
# $DVIPS = "dvips -r0";


# Location of texexpand, supplied with the translator
$TEXEXPAND = "$LATEX2HTMLDIR/texexpand";


# Location of pstoimg, supplied with the translator
$PSTOIMG = "$LATEX2HTMLDIR/pstoimg";


# This is used to "autoload" perl code to deal with specific style files
$LATEX2HTMLSTYLES = "$LATEX2HTMLDIR/styles";


# This is used to support upcoming versions of html - directory where perl
# files to handle those are
$LATEX2HTMLVERSIONS = "$LATEX2HTMLDIR/versions";


# The following variable sets the default search list of directories for
# latex style files that latex2html should process.  It also defines a
# a list of directories (: separated) which possibly contain TeX and dvips
# inputs.  This variable is overriden by the environment variable
# TEXINPUTS, if it is specified.  Internally, the directory your document
# resides in, and ".", are appended to this list of directories.
#
#  IMPORTANT:  In some installations, latex and dvips are really
#  shell scripts which set environment TEXINPUTS (and other variables)
#  to predefined values, then call the real latex and dvips.  If this
#  is true for your installation, then the $TEXINPUTS that latex2html
#  sees will only affect the processing of \input and \include's
#  by latex2html, not the operation of latex and dvips when called
#  by latex2html.  In this case, make sure that the predefined
#  values of TEXINPUTS within the latex and dvips scripts at least
#  contains "." and ".." (".." works in the most cases).
#  Otherwise, latex and dvips will not find inputs from the original source
#  directory when called from a subdirectory contained therein.
#
# The single colon tells LaTeX to look on the standard places only.
# If you add entries, do it colon-separated.
# If you don't know where LaTeX takes its standard files from, leave the
# single colon in front or at the end, or have an empty entry "::"
# at some place among the other entries.
$TEXINPUTS = "/usr/local/lib/tex/inputs/:";

# This line helps LaTeX2HTML to recognize your adaption everywhere.
$ENV{'TEXINPUTS'} = $TEXINPUTS unless defined $ENV{'TEXINPUTS'};

# 'install-test' does *not* check whether PK_GENERATION will work.
# If any of it causes you grief, simply set PK_GENERATION=0,

#  understands the "-mode" command line switch.  It is a more reliable
#  way of setting the METAfont mode than the .dvips file on versions that

# A file 'modes.mf' is probably installed somewhere in your tex
# tree. e.g /usr/local/tex/texmf/mf/modes.mf or something similar.
# If it has and entry for 'toshiba', then you can ignore the rest.
# Otherwise, you'll need to try *one* of the following things:
#
#  o Set PK_GENERATION=0 and generate images for your default printer
#  o Download the latest modes.mf from the TeX archive and re-run inimf.
#  o Choose another LOW RESOLUTION screen or printer entry from modes.mf,
#    (preferably with "|blacker|" set to 0.0 and a 1:1 aspect ratio--
#     If you don't have "toshiba", try "epsonlq", "lqlores", "nec", or "NEC")
#     If you try some other mode, remember to update two other things as well:
#
#      1) Change the 'toshiba' in the .dvipsrc file that came with latex2html.
#      2) Put whatever the |pixels_per_inch| value is into $METAFONT_DPI
#         and the .dvipsrc file
#
#   Note: The maximum usable SCALE_FACTOR is determined by this resolution.
#   A higher resolution will take more memory during processing (regardless
#   of SCALE_FACTOR) but will allow higher SCALE_FACTORs.  Do NOT just
#   change this value though.  It *must* match the |pixels_per_inch| of
#   the metafont mode (e.g. `toshiba').

### Verbosity #################################################################
#
# The amount of message information printed to the screen during processing
# by LaTeX2HTML is controlled by the $VERBOSITY variable.
# Its value can also be set using the  -verbosity <num>  command-line switch.
# By increasing this value, more information is displayed.
# Here is the type of extra information that is shown at each level:
#
# $VERBOSITY = 0;	# no extra information
# $VERBOSITY = 1;	# section types and titles
# $VERBOSITY = 2;	# environment
# $VERBOSITY = 3;	# command names
# $VERBOSITY = 4;	# links, labels and internal sectioning codes
#

### Navigation Panel ##########################################################
#
# The navigation panel is constructed out of buttons and section titles.
# These can be configured in any combination with arbitrary text and 
# HTML tags interspersed between them. 
# The buttons available are:
# $PREVIOUS - points to the previous section
# $UP  - points up to the "parent" section
# $NEXT - points to the next section
# $NEXT_GROUP - points to the next "group" section
# $PREVIOUS_GROUP - points to the previous "group" section
# $CONTENTS - points to the contents page if there is one
# $INDEX - points to the index page if there is one
#
# If the corresponding section exists the button will contain an
# active link to that section. If the corresponding section does
# not exist the button will be inactive.
#
# Also for each of the $PREVIOUS $UP $NEXT $NEXT_GROUP and $PREVIOUS_GROUP
# buttons there are equivalent $PREVIOUS_TITLE, $UP_TITLE, etc variables
# which contain the titles of their corresponding sections. 
# Each title is empty if there is no corresponding section.
#
# The subroutine below constructs the navigation panel in each page.
# Feel free to mix and match buttons, titles, your own text, your logos,
# and arbitrary HTML (the "." is the Perl concatenation operator).
#JKR: Use two panels (top and bot) instead of one.

### ASCII Mode ###########################################################

# This subroutine defines the ascii strings to be used instead of the 
# icons when the translator is invoked with the -ascii_mode option.
# Please modify them if you do not like them, BUT 
# *** DO NOT USE THE SPACE CHARACTER (" ") FOR $anchor_invisible_mark ***
# (if you use " " then the cross-reference hyperlinks will not work).

### Adding commands to be ignored ########################################

# Add LaTeX commands to be ignored.
# Each command should be on a separate line and have the format:
#  <cmd_name>#{}# []# {}# [] etc. 
# {} marks a compulsory argument and [] an  optional one.
# Note that some commands may have arguments which should be left as
# text even though the command should be ignored (e.g. mbox, center, etc)

&ignore_commands( <<_IGNORED_CMDS_);
htmlrule # [] # \$_ = join('',"<BR><HR>",\$_) 
mathversion # {} 
underline # {} # \$_ = join('',"<U>", \$2, "</U>", \$_)
centerline # {} # \$_ = join('',"<P ALIGN=CENTER>", \$2, "</P>", \$_)
latexhtml# {}
latex# {}
html
lrule # {} 
scrollmode
savebox# {}# []# [] 
center
citeindexfalse
_IGNORED_CMDS_


### Adding commands to be processed by TeX ###############################

# Commands which need to be passed, ALONG WITH THEIR ARGUMENTS, to TeX.
# The syntax is the same as that for ignore_commands above.

&process_commands_in_tex (<<_RAW_ARG_CMDS_);
fbox # {}
framebox # [] # [] # {}
