Version 1.03 provides fixes for two bugs reported by Volker Kuhlmann ("<MAP>"
causes a CORE dump; "<A NAME=xxx>" causes the whole document being
underlined), and also other fixes, as denoted below.

Also, attributes with textual values (like "ALIGN=RIGHT") were not processed
case-insensitively.

**************************************

----------------------------
Allow paragraph content in heading.
----------------------------
Removed "auto_aptr::operator const void *()" and "operator!()".
----------------------------
"Body::unparse()" and "Body::format()" were not virtual, so THs were
unparsed and formatted as TDs.
----------------------------
Removed "auto_ptr<T>::operator=(T *)" for ANSI C++ compatibility.
Non-inlined "HTMLParser::~HTMLParser()" to work around an EGCS bug.
----------------------------
Added "$EXPLICIT".
----------------------------
Removed "auto_ptr<T>::operator=(T *)" for ANSI C++ compatibility.
Non-inlined "Element::~Element()" to work around an EGCS bug.
----------------------------
"Option.pcdata" is now an "auto_ptr" (memory leak).
----------------------------
Removed "auto_ptr<T>::operator=(T *)" for ANSI C++ compatibility.
----------------------------
Added "/usr/include/g++-2" to the MAKEDEPEND include path.
----------------------------
Added "cmp_nocase()". Swallow empty list items. Do not underline anchors
that have no HREF.
----------------------------
The "get_attribute()" variants that compare attribute values against strings
now compare case-insensitively. Added "cmp_nocase()".
----------------------------
Added multiple-inclusion protection code. Added "cmp_nocase()".
----------------------------
"Area::add_attribute()": Do not add attribute to left and right free areas.
----------------------------
Typo: "ALIGN" attribute of "<TR>" and "<TD>" was misspelled "HALIGN".

**************************************


                         #############################
                         #                           #
                         #  Changes in Version 1.04  #

                         #############################

Ported to EGCS 2.91.66 and SINIX CDS++ 2.00A00.

**************************************

----------------------------
Improved generation of $MAKEDEPEND_INCLUDES: Now we use "$(CXX) -E" and
look at the "#line" directives to find out where the C++ compiler found
"#include <iostream.h>".
----------------------------
Removed a useless CONST qualifier in "libstd/include/string".
----------------------------
Cleaned up the make file.
----------------------------
"libstd/Makefile" is now only created when "./libstd" is actually needed.
----------------------------
Port to CDS++ 2.0: "string::operator[]()" is a bit picky... fixed.
----------------------------
Replaced "$(HAS_AUTO_PTR)" with "$(HAS_WORKING_AUTO_PTR)" -- "EGCS 2.91.66"'s
implementation of "auto_ptr" is buggy!

**************************************


                         ############################
                         #                          #

                         ############################

The formatting of HTML2TEXT is now largely customizable through the
"$HOME/.html2textrc" file.

----------------------------
Inlined "Area::append()".
----------------------------
Optimized "Area::operator>>=()".
----------------------------
Formatting is now (partly) customizable, as proposed by Rolf Niepraschk.
Added some missing copyright notices.
----------------------------
The default <UL> / <DIR> / <MENU> bullet style now depends on the list nesting l
evel.
----------------------------
"Properties" now handles escape sequences.
----------------------------
Added "cmp_nocase()".
----------------------------
Added multiple-inclusion protection code. Added "cmp_nocase()".
----------------------------
Added new formatting properties.
----------------------------
Empty "HR.marker" now maps to a blank marker. Do not break lines at ",.;:".
Break lines at "([{".
----------------------------
Added three custom bullet types.
----------------------------
[e-mail]: HTML2TEXT hangs when it encounters a "<TD COLSPAN=99>",
because for HTML2TEXT table columns are separated by blanks, and 99 blanks
are wider than 79 characters.
----------------------------
"urlistream" now strips "#anchor" suffixes from URLs.
----------------------------
[e-mail]: egcs-2.91.66 complains that "list::reverse_iterator" must
not modify private "list::iterator::node".
----------------------------
Added man page for "html2textrc".
----------------------------

                         ##############################


----------------------------
Removed the "STRING_ERASE" crap -- don't use G++ 2.7.2.1 Standard C++ Library
any more!
----------------------------
Renamed "HAS_SYS_POLL" to "SYS_POLL_MISSING" and "HAS_AUTO_PTR" to
"AUTO_PTR_BROKEN".
----------------------------
Added HAS_SYS_POLL, because Linux 2.0.35 does not provide <sys/poll.h>.
----------------------------
Removed the "tar-file" target and added a "make-tar-file" shell script.
----------------------------
CONFIGURE now uses $CXX instead of "cc" to check <sys/poll.h> and the socket
libraries. The TMP dir is no longer "/tmp", but "./configure-tmp".
----------------------------
Replaced "echo -n" with "echo xxx\c". G++ 2.95.1 has problems with auto_ptrs
and lists (see "configure").
----------------------------
Bug: Narrow table cells were not formatted properly.
----------------------------
Default format for <MENU> is now NO_BULLET / indent 2. Corrected indentation
for <DT> / <DD>.
----------------------------
Added VSPACEs/INDENTs for <DT> and <DD>.
----------------------------
Fixed a formatting bug concerning <PRE> (ROlf Niepraschk, Nov 8 1999, 12:51).
----------------------------
Performance optimization: Do temporary table cell formatting always left
aligned.
----------------------------
G++ 2.7.2.1 fails to compile "multimap::equal_range()" for some unknown
reason -- commented out.
----------------------------
Need a dummy "value_type" typedef for "vector" -- else G++ 2.7.2.1 fails to
compile.
