release candidate for latex2rtf

Hey all,

Here is a release candidate of latex2rtf.  This release is driven by
extensive testing done by Wilfried who uncovered a disconcerting number
of bugs.  These are now fixed and the new candidate is at

   http://omlc.ogi.edu/software/tex_convert/latex2rtf-1.9.19.tar.gz

One issue that merits further discussion is that this release has a new
restriction: any files used by the root latex document must be contained
somewhere in the directory of the root document.  This is similar to how
TeX itself works.  Absolute paths don't work anymore.  There has been  
a bug
report about both behaviors.  Who thinks that this is an unnecessary  
restriction?

The 1.9.19 release also eliminates the rarely used '%latex2rtf:'  
sequence to
pass commands directly to latex2rtf (and hide them from latex).  Instead
use the much more powerful '\iflatextortf ... \else ... \fi' sequence.

New features (since 1.9.18) include

  * basic support for \usepackage{subfigure}
  * basic support for \usepackage{endfloat}
  * basic support for \documentclass{apa}
  * basic support for \usepackage{pstricks-add}
  * basic support for \usepackage{hyperref}
  * nearly complete support for \usepackage{apacite}

  * support for \symbol{\'23} and better support for \char'23
  * support for \overrightarrow
  * support for \namedref
  * support for \urlstyle and \UrlFont

********************  ChangeLog  ***********************************

r752 support \symbol{\'23} and \symbol{\"13}.  Improve \char'23 so that
      it changes if\tt is active

r753 support \char92 and \char`b and \symbol{92}

r754 rip out support for %latex2rtf: as a way of controlling parser.
      Replace uses in examples with \iflatex2rtf ... \else ... \fi.  Fix
      mistake in getSimpleCommand() that did not allow '\!' to be
      returned. Eliminate weird bug when a command follows an integral
      sign ... $\int \cos$. Improve debugging output at -d2 level.

r755 Do not try to ignore packages or package options.

r756 Fixes for the regressions in overstrike.tex

r757 WH: commented out unneeded 'show_buffer' function in preparse.c

r758 add \urlstyle{} ignore.cfg.  Cleaned up TryIgnoreVariable().  Made
      arguments to strdup_together be constant strings.  More of this
      should be done.

r759 silence \renewcommand{}{} warning.

r760 no functional change ... just different code comment

r762 Improve documentation for \iflatextortf and provide work-around for
      %latex2rtf:

r763 Fix for backslash-linefeed problem in .aux files.  Pretty obscure.

r764 Suppress multiple warnings for missing \bibcite{} entries.  Change
      Makefile in test directory to sup press all the output from latex.

r765 WH: modified cfg.c so that latex2rtf also tries to find the cfg dir
      in C:\%ProgramFiles%\latex2rtf\cfg (default if installed by  
windows
      installer)

r766 Fix typo in diagnotic message for \ensureeqn.  Fix Makefile for
      bib_super.tex. Revise my_fgetc() in the hopes of making it more
      portable.  Update ScanBbl() so that it uses the new routine.

r767 Fix regressions in bib_natbib1.tex and bib_natbib2.tex.  Don't know
      where this code went, but the use of plain old \cite{} in the
      natbib style was broken.

r768 Add tests for \documentclass{apa}

r769 Make section headers bold for \documentclass{apa}

r770 Fix the bug from the preamble of bib_apa.  Add 'const' to more
      functions. Eliminate all unneeded fprintf(stderr,...).  Rename a
      bunch of diagnostic(1,...) instances to diagnostic(WARNING, ...).

r771 Adding two more test files

r772 WH: Modified main.c so that -P option now works also under
      DOS/Windows. Updated documentation of -P option and -M option.
      Fixed bug in latex2png script.

r773 WH: Updated documentation of -P option and -M option (again).

r774 added diagnostic() line to my_fgets() to help sort out the problems
      on Windows.

r775 WH: xrefs.c: Open aux file in binary mode. Removed extra
      diagnostic() line.

r776 Use fprintf() in show_string() to produce better diagnostics

r777 Fix for bibentry_apalike.tex

r778 Make sure all fopen() calls use the mode "rb"

r779 Starting the process of rationalizing the debug levels

r780 remove a few instances of strcat

r781 More clean-up of debugging information.  -d2 now shows nothing but
      file manipulations.  Small tweaks to makefile in the test  
directory
      to create temporary files in a folder within the current  
directory.

r782 More diagnostics clean-up.  It is now possible to get relatively
      noise-free output using -d2.  This diagnostic level shows file
      handling and each section as it is handled.  The plan is to make
      -d3 echo system commands and each section as it is preparsed.  -d4
      will track each \command as it is used.

r783 More rationalization for debugging levels.  One day -d5 will be
      stuff that happens within CmdName() functions and -d6 will show
      nearly everything but character processing, and -d7 will show each
      character as it gets read and processed.

r784 Fix for fig_endfloat conversion.  It mostly works.  A few more
      diagnostic() tweaks.

r785 More diagnostics() tweaks.

r786 support \overrightarrow

r787 preliminary support for subfigure package

r788 test file for \subfigure[caption]{figure} command

r789 Add proper paragraph ending to subfigure pieces.  Fix numbering of
      subfigures.  Add tests.

r790 Initial code to support the pstricks-add package.  Three commands
      are recognized \psset{}, \begin{psgraph}, and \begin{pspicture}.
      One broken test file (at least I cannot latex it successfully) is
      also included.

r791 Emit information as latex2rtf is doing slow stuff (converting
      latex->PNG or pdf->PNG).  Eliminate first linefeed and emit a  
final
      linefeed when done.  This helps to group the output with the
      previous command.

r792 Clean up a few preamble problems in the test documents.

r793 revert to placing the DOCUMENT_MODE environment before PREAMBLE
      because there was no real reason to change and this might  
introduce
      new subtle bugs.

r794 add support for \href{url}{text}, \url{url}, \nolinkurl{url}.

r795 start of a test file for hyperref features

r796 refactoring the hyperlink code

r797 more \url{ref} clean-up.  add putRtfStrEscaped() function.

r798 eliminate some compiler warnings

r799 Minor change to getRawTexChar() to handle EOF condition better.
      Small change to CmdInclude() to properly terminate with long file
      names.

r800 Make is so that long file names fail properly when \input is used.
      Extend the possible file name length to 99.

r801 Fix bug in ScanAux() so that it handles \@input{file} properly.
      Enhance test/include.tex so that it can be properly processed by
      latex.  Add pagebreak before every instance of \include{file} as
      should be done.  Fix minor bug in subsubsection numbering when
      section but not subsection is used.

r802 preliminary code to support \newpsstyle{}{} ... unclear if it works
      yet.

r803 remove debugging commands since \newpsstyle{}{} seems to work.  Add
      more packages with 'limited' support.  Have a number of test files
      run latex first to generate .aux files.  Improve diagnostics for
      writelatexasbitmap().

r804 silently ignore \nobreak, \expandafter, \long.  Change warnings
      from 'ignored' to 'unknown'.  More general cleanup.

r805 WH: fixed a bug in main.c. Updated documentation.

r806 WH: fixed my bugfix in main.c (should have tested it before
      uploading!)

r807 Minor clean-up of -se# and -sf# scaling options.  We don't properly
      support long option names, currently '-se #' is an error.
